Introducing the new bootc kickstart command in Anaconda

Anaconda installer now supports installation of bootc based bootable container images using the new bootc command. It has supported several types of payload to populate the root file system during installation. These include RPM packages (likely the most widely used option), tarball images you may know from Fedora Workstation, ostree, and rpm-ostree containers. The newest addition to the family, from a couple of weeks ago, is bootc-based bootable containers.

The difference is under the hood

We have added a new bootc kickstart command to Anaconda to support the new feature. This is very similar to the ostreecontainer command that has been present for some time. From the user’s perspective the two are very similar. The main difference, however, is under the hood.

One of the most important setup steps for a deployment is to create a requested partitioning in both cases. When the partitioning is ready, the ostreecontainer command makes Anaconda deploy the image onto the root filesystem using the ostree tool. It also executes the bootupctl tool to install and set up the bootloader. By contrast, with bootc containers installed using the bootc kickstart command, both the filesystem population and bootloader configuration is performed via the bootc tool. This makes the deployment process even more integrated.

The content of the container images used for installation is another difference. The bootc-enabled images are somewhat more versatile. Apart from installation using Anaconda, they provide a self-installing option via the bootc command executed from within a running container.

On the other hand, both options provide you with a way to install an immutable system based on a container image. This option may be useful for particular use cases where regular installation from RPM packages is not desired. This might be due to potentially lower deployment speed or inherent mutability of the resulting system.

A simple how-to

In practice, you’d likely use a custom container with pre-configured services, user accounts and other configuration bits and pieces. However, if you want to quickly try out how the new Anaconda’s feature works, you just need to follow a few simple steps. Starting with a Fedora Rawhide ISO:

First, take an existing container from a registry and create a minimal kickstart file instructing Anaconda to install the bootable container image:

# Beware that this kickstart file will wipe out the existing disk partitions.
# Use it only in an experimental/isolated environment or edit it accordingly!
zerombr
clearpart --all --initlabel
autopart lang en_US.UTF-8
keyboard us timezone America/New_York --utc
rootpw changeme bootc --source-imgref=registry:quay.io/fedora/fedora-bootc:rawhide

As a next step, place the kickstart file in some reachable location (e. g. HTTP server), point Anaconda to it by appending the following on the kernel command line:

inst.ks=http://url/to/kickstart 

Now start the installation.

Alternatively, you may use the mkksiso tool provided by the lorax package to embed the kickstart file into the installation ISO.

When installation and reboot is complete, you are presented with an immutable Fedora Rawhide system. It will be running on your hardware (or VM) installed from a bootable container image.

Is there anything more about bootc in Anaconda?

You may ask if this option is limited to Fedora Rawhide container images. Technically speaking, you can use the Fedora Rawhide installation ISO to install, for instance, a CentOS Stream container image:

bootc --source-imgref=registry:quay.io/centos-bootc/centos-bootc:stream10

Nevertheless, keep in mind that for now Anaconda will handle it as Fedora installation in such a case. This is because it runs from a Fedora Rawhide boot ISO. This may result in unforeseen problems, such as getting a btrfs-based partitioning that CentOS Stream won’t be able to boot from. This particular issue is easily overcome by explicitly telling Anaconda to use some different partitioning type, e. g. autopart –fstype=xfs. We would like to address the lack of container images handling based on the contained operating system or flavour in the future. For now, one just needs to take the current behavior into consideration when using the bootc command.

There are a couple more known limitations in Anaconda or bootc at this point in time. These include lack of support for partitioning setups spanning multiple disks, support for arbitrary mount points, or for installation from authenticated registries. But we hope it won’t take long to solve those shortcomings. There are also plans to make the new bootc command available even on the RHEL-10 platform.

We invite you to try out this new feature and share your experience, ideas or comments with the Installer team. We are looking forward to hearing from you in a thread on discussion.fedoraproject.org!

Creating Data Analysis Pipelines using DuckDB and RStudio

Motivation and Vision

The core motivation behind data analysis pipelines, and the focus of this article, is the need to establish a clear path from unprocessed data to actionable insights for contributor engagement and impact. The key question is “what are we trying to measure to ensure the continuity of community work?”

As a side note, my preparation for the ADSP (Advanced Data Analysis Semi-Professional) certification in Korea utilized RStudio Desktop, running on a Fedora Linux environment. I got hands-on with R’s core statistical toolkit, leveraging base functions. Among these were summary()1 and lm()2 as the basis for fundamental hypothesis testing and regression analysis3. I became more intrigued by R’s power after testing its data manipulation packages (especially the key package dplyr).

With this background in mind, the article focuses on the design of an analysis pipeline that fulfills three objectives:

  • it leverages the power of DuckDB4 and S3 storage,
  • it redefines the workflow,
  • it ensures scalable data transformation and analysis capabilities

Establishing such a robust foundation is essential for producing reliable and validated metrics for the contributor community, which itself is subject to ongoing definition and validation.

Acknowledgement: I extend my sincere gratitude to Justin Wheeler for connecting me with the Fedora Data Working Group (FDWG), and to Michael Winters and K Naraian for their guidance, discussion, and support throughout the design and validation of this data analysis pipeline.

Scope and Tool Selection: Please note that this analysis pipeline represents a combination of tools and methods chosen from my perspective as a data analyst, particularly one with a background in the CRM (Customer Relationship Management) domain and consumer electronics industry. Therefore, other analysts or data engineers may utilize different combinations of technologies based on their own expertise or project requirements.

Why data analysts must engage with ELT5/ETL6

The role of the analyst is undergoing a fundamental transformation in 2025. We are moving beyond the traditional responsibility of performing statistical analysis and presenting visualization on pre-cleaned data. Today, the modern analyst must evolve into a “Data Ops(Operations)”. This requires a holistic understanding of the data lifecycle and bridging the gap between business context and data engineering. This expansion mandates a familiarity with ELT/ETL processes to examine the quality and structure of the data source.

Moreover, data analysts must be adept at processing diverse data types such as semi-structured data (for example, schema-less JSON strings or variant) and understanding various data access methods such as leveraging the efficiency of in-situ processing over the constraints of in-memory loading of datasets.

RStudio: The Unified IDE for Hybrid R and Python workflows

My ADSP examination requirements motivated my initial deep dive into RStudio. However, it is worth highlighting its utility as a tool for any data professional. The most significant benefit of using RStudio is its seamless ability to leverage the best tools from both the R and Python language ecosystems. This eliminates the need for the analyst to switch environments which leads to dramatically higher operational efficiency. This unified approach streamlines the analysis lifecycle from code execution to final reporting.

Python for data engineering

Use Python’s libraries like Pandas for efficient ETL/ELT operations, data manipulation on large datasets, and integrating with production environments or machine learning workflows (TensorFlow/PyTorch).

R for analysis and visualization

Utilize R’s statistical packages and its superior data visualization capabilities (ggplot2, R Shiny) for data analysis modeling, beautiful reporting, and creating customized, publication-ready graphics.

RStudio Desktop: Installation Instructions7 for Fedora Linux

Install R base packages using the terminal and verify:

$ sudo dnf install R
$ R --version

Now, install RStudio from the Fedora COPR repository. Note that these COPR packages conflict with the binary package provided by Posit. Remove the existing Posit RStudio binary package if you installed it.

$ sudo dnf copr enable iucar/rstudio
$ sudo dnf install rstudio-desktop

Dependencies and dev tools are required so install them:

$ sudo dnf install @development-tools
$ sudo dnf install libxml2-devel openssl-devel curl-devel

Launch the RStudio. When the < prompt appears on the RStudio Console enter the following commands. Note that this prompt should appear in the bottom-left pane of the default layout.

Install the reticulate package and execute the function reticulate::py_install() to manage Python dependencies:

install.packages("reticulate")
reticulate::py_install(packages = c("duckdb", "pandas"))

Set the global options for all code chunks within the R Markdown Canvas:

knitr::opts_chunk$set(echo = TRUE, message = FALSE, warning = FALSE)

ragg is an indirect but critical dependency of core Tidyverse packages (such as ggplot2):

install.packages("ragg")

Install base packages for data manipulation:

install.packages("tidyverse")

DBI, tools for database interface, is an essential R package that provides a standardized, vendor-agnostic interface for connecting to and interacting with various database systems (both local and remote)

install.packages("DBI")

Install tools for Parquet files and S3 data lake access:

install.packages("arrow")

Install R Markdown for combining R code, and install Quarto for combining R/Python/SQL with its execution results, and explanatory text into reproducible data pipelines directly within the environment. The Quarto (.qmd) file runs code chunks in R, Python, and SQL in a single document.

install.packages(c("rmarkdown","quarto"))

Load packages for ELT and EDA:

library(tidyverse)
library(arrow)

Data architecture pipeline

The specific dataset chosen, Datanommer (Fedora Messaging Streams), aligns with the strategic objectives of the Fedora Data Working Group, where I contribute. The data is stored in the Bronze Data Layer where raw data from source systems is ingested and stored, as-is, for scalable data lake storage. The Bronze Layer allows for schema evolution without breaking downstream processes.

To provide the Working Group with transparent access and initial insight into this data, I have prepared a shared Initial Exploratory Data Analysis (EDA) Notebook. This notebook serves as the initial public view of the data quality and patterns, and it informed the subsequent architectural decisions for the scalable pipeline I am about to outline.

Given the complexity of the architecture, I will proceed with an outline of the core components, organized by their role in the ELT pipeline:

Data Architecture Diagram: Assisted by Figma ‘Infinite Canvas’

This restructured pipeline, leveraging the new Lakehouse architecture, unlocks several core benefits crucial for scaling contributor analysis and enabling future insights:

Elimination of Memory Constraints via In-Situ Processing

DuckDB acts as a high-performance analytical engine that enables In-Situ Processing. It queries data directly from storage (specifically the Parquet files) without requiring the entire dataset to be loaded into RAM. This not only solves the memory problem but also delivers rapid query execution and significantly lowers operational costs associated with large computational clusters hosted on the OpenShift/Fedora AWS infrastructure.

Quarto runs R code chunks to connect to DuckDB

Future-Proofing

The shift to a Lakehouse model ensures the pipeline is ready for growth and evolving data complexity. Future integration of Apache Iceberg and Apache Polaris will provide schema evolution capabilities. This ensures the pipeline is fully future-proofed against changes in underlying data structures.

Streamlined ELT Workflow and Multi-Lingual Access

I have redefined the processing workflow from a bottlenecked ETL model to a resilient Extract-Load-Transform (ELT) pattern. Parquet files with the variant type store semi-structured data (like JSON/nested structures), loaded raw into S3, simplifies the ingestion stage. When using R, it is recommended to read Parquet files using the Apache Arrow library.

Exploratory Data Analysis (EDA) using data frames in the Tidyverse

The parsed data is then accessible by multiple analytical platforms (R Shiny, Python, BI tools) without duplication or manual preparation. This multi-lingual access maximizes the utility of the clean data layer, supporting a growing number of analytical users and more complex queries necessary for defining long-term contributor metrics.

Initial EDA Notebook

The preliminary Exploratory Data Analysis (EDA) was conducted within the Jupyter Notebook format. This allowed broad compatibility with the existing execution and review environment of the Fedora Data Working Group.

The Initial EDA Notebook is documented to ensure complete reproducibility. This included all necessary steps for the Python library installation and environment setup. Any standard Python script containing ELT logic can be seamlessly run within RStudio’s Python mode or “knitting8” an R Markdown document or rendering a Quarto file.

Conclusion

The establishment of this analysis pipeline represents a crucial step in transforming unprocessed Fedora data into actionable insights. By addressing the core challenges of scaling and in-memory processing through DuckDB, and enabling transparent analysis via the hybrid RStudio/Jupyter workflow, I have demonstrated viable methods for performing Exploratory Data Analysis (EDA) and Extract, Load, Transform (ELT) processes on vast community datasets. In conclusion, the purpose of this work is to foster deeper engagement across a broader community by analyzing data with a view that relates to the Fedora Project community.

I hope this pipeline will serve as the technical foundation that activates and focuses the community discussion around the specific variables and metrics needed to define and ensure the continuity of community contributions.

RStudio Desktop 2025.05.1 Build 513 (Fedora COPR repository)

R version 4.5.2 (2025-10-31) / Python 3.14.0

Notes

  1. summary(): When used on a data object (for example, DataFrame), it provides basic statistics (min, max, mean, median). When used on a fitted linear model object (lm), it delivers key diagnostic information like coefficient estimates and p-values. ↩
  2. lm(): Stands for Linear Model. This is the core function for fitting linear regression models in R, allowing the user to examine and model the linear relationship between variables. ↩
  3. Regression analysis examines which factors affect the other and which ones are irrelevant for statistical and business context. ↩
  4. DuckDB is a column-oriented database architecture.
    – Direct Querying: It directly queries data from file formats such as Parquet, CSV, and JSON.
    – Local compute engine: It is widely used as a high-performance local compute engine for analytical workloads. It runs in-process, meaning it operates within your application (like a Python script or R session) without needing a separate server or cluster management.
    – Cloud Integration: It supports querying data stored in cloud storage services like AWS S3, GCS (Google Cloud Storage), and Azure Blob Storage.
    ↩
  5. ELT (Extract, Load, Transform): In a modern data environment like a Lakehouse, ELT is preferred: data is first extracted from the source and loaded raw into the cloud data lake (S3), and then transformed in place by the processing engine like DuckDB. ↩
  6. ETL (Extract, Transform, Load): transformations occur before loading the data into the final destination. ↩
  7. Key Advantages of RStudio over Jupyter Notebook for Production Workflows;

    Even with its slightly more complex initial setup compared to Jupyter Notebooks, the advantages become significant when moving from exploration (Jupyter’s strength) to reproducible, production-ready workflows (RStudio’s strength).

    – Integrated Console, Source, Environment, and Files: RStudio offers a cohesive, four-pane layout that allows for seamless navigation between writing code, running commands, inspecting variables, and managing files/plots. Jupyter requires constant shifting between code cells and external tabs.
    – Superior Debugging Tools: RStudio includes a powerful, visual debugger that allows you to set breakpoints, step through code line-by-line, and inspect variable states directly in the environment pane. Jupyter’s debugging is typically cell-based and less intuitive.
    – Native Project Management: RStudio Projects (.Rproj files) automatically manage the working directory and history. This makes it easy to switch between different analytical tasks without conflicts.
    – Integrated Environment Management (renv): RStudio integrates seamlessly with tools like renv (R Environment) to create isolated, reproducible R environments. This addresses dependency hell by ensuring the exact package versions used in development are used in production, which is crucial for data pipeline version control.
    – Quarto/R Markdown Integration: RStudio provides dedicated tools and buttons for easily compiling and rendering complex analytical documents (like your Quarto file) into HTML, PDF, or presentation slides.
    – Shiny Integration: RStudio is the native environment for developing Shiny web applications—interactive dashboards and tools that turn analysis into deployable products. Jupyter requires separate frameworks (like Dash or Streamlit) for similar deployment.
    – Focus on Scripting: RStudio’s source editor is optimized for writing clean, structured R/Python scripts, which are preferred for building robust, scheduled pipeline components (like those managed by Airflow).
    – Code Chunk Execution (Quarto): Even when using Quarto, RStudio allows for superior navigation and execution of code chunks compared to the often sequential and state-dependent nature of Jupyter Notebook cells. ↩

  8. knitr executes code in R Markdown (.Rmd) file by chunks or as a whole (typically by clicking the “Knit” button in RStudio or using rmarkdown::render() in R) ↩

Talk to your Fedora system with the linux-mcp-server!

Talk to your Fedora system with the Linux MCP Server!

Generative AI systems are changing the way people interact with computers. MCP (model context protocol) is a way that enables LLMs to run commands and use tools to enable live, conversational interaction with systems. Using the new linux-mcp-server, let’s walk through how you can talk with your Fedora system for understanding your system and getting help troubleshooting it!

Introduction

 Large language models (LLMs) can be an invaluable tool when investigating an issue on a Linux system. However, this can involve a lot of copy/pasting of information from the Linux terminal into a web based interface to an LLM model.  

The model context protocol (MCP) acts as a bridge, enabling LLMs to interact with external tools and data sources.  The linux-mcp-server utilizes this protocol to give LLMs the ability to interact with a Fedora Linux system.  Instead of you manually copying and pasting terminal output, the linux-mcp-server enables the LLM to directly query system information and log entries.  

By enabling an LLM direct access to system information and logs, it is transformed into an active part of the investigation process when troubleshooting an issue.  It empowers an LLM to directly query the system state, allowing it to help identify performance bottlenecks, and identify important log entries that might be missed by a manual review.  

What is the model context protocol (MCP)?

Anthropic introduced MCP in November 2024 as an open standard for LLM tool use. This provides a way for LLMs to interact with outside systems and data sources.  

Prior to MCP,  there wasn’t as strong a standard and ecosystem for LLM systems to call tools. LLMs were thus frequently limited to have only the information contained in their training. They were isolated from the outside world.  For example, if you asked an LLM “what is the weather going to be next week”, the LLM would respond with a message indicating that it doesn’t know what the weather will be, as it doesn’t have access to that information. MCP helps solve this problem by enabling a standardized way for an LLM to access an outside data source, such as the weather forecast.   

At a high level, users can use an AI agent application, such as Goose (open source), or Claude Desktop, and specify which MCP servers they would like to use.  The AI agent application informs the LLM that there are tools available via these MCP servers that can be used to help answer the requests from the user. The LLM model can then decide when to invoke these tools.  

MCP is an open standard. You have the flexibility to use MCP servers, such as linux-mcp-server, with either open source-licensed LLM models, or hosted proprietary LLM models. 

What is the linux-mcp-server?

The linux-mcp-server is a project started by Red Hat’s RHEL Engineering team.  It provides a number of tools that enable an LLM to query information from a Linux system, such as system info, service information and logs, process information, journald and other logs, network information, and storage and disk information.  For a full list of the tools provided, refer to the project’s Github page.  

These tools, provided by linux-mcp-server, are focused on providing the LLM access to read-only information.  In the future, we’ll be exploring expanding past these read-only use cases.  

The linux-mcp-server can be used to interact with the local Fedora Linux system that it is running on. It can also be used to interact with remote Fedora Linux systems over SSH.  For example, if you have SSH key authentication setup with the remote systems, you could make a request to your AI agent application such as “Determine the current memory usage on the fedora1.example.com, fedora2.example.com, and fedora3.example.com servers”.  

Prerequisites

The main components needed are an AI agent application, access to LLM model inference, and the linux-mcp-server. 

There are a number of options for the AI agent application, both open source and proprietary.  An example of an open source AI agent is Goose, which provides an RPM that can be installed on Fedora.

There are several LLM model inference options, ranging from locally hosted open source models, to proprietary hosted LLM models.  If hosting a model locally, you generally need to have GPU/accelerator hardware available.  Open source tools that can be used to locally host LLM models include RamaLama, llama.cpp, and Ollama. There are a number of open source LLM models capable of tool calling. These include models such as gpt-oss-20b and Granite 4 small.

Once you’ve installed your preferred AI agent application, the next step is to install the linux-mcp-server and configure your AI agent application to use it. The linux-mcp-server Github page includes installation instructions, and configuration details for Goose and Claude Desktop.

Use cases for linux-mcp-server

⚠ NOTE

The example scenarios below include LLM generated output. The output is presented here as it was generated by the AI systems cited so you can assess the quality of the output they are capable of, particularly in a non-cloud, self-hosted scenario.

The sample LLM output provided here is not intended to be run by readers without the same level of review we recommend anyone perform on AI generated content prior to use on their systems.

Dear Fedora, why are you so slow today?

Has this happened to you? Time to hop on a call and give a demo. You’re pumped. It’s your go-time aaaaand… your system starts lagging. Folks on the call say your video is choppy or they can’t understand you. OH NO.

You’ve got to assess what’s up, quickly. Run `top`, check `dmesg`, check your network connection (read the man page for `netstat` because you can’t remember the flag you want), check `journalctl`, cross-reference what you’re seeing, then start killing processes, restarting services, reloading kernel modules willy-nilly based on hastily-crafted theories, see if it improves… 

This is a case where you could actually ask the system to tell you why it’s slow and give it the ability to do the analysis via linux-mcp-tools. The LLM you connect with won’t just run the commands through the MCP server; it will understand what the numbers it gets means in context and be able to explain in human terms.

So let’s start working with a relatively new laptop. It’s a Thinkpad T14S with the AMD Ryzen™ AI Pro 7  ( Ryzen™ AI 360 chip.) Recently one of the wifi networks it must connect to regularly was upgraded. It now has  issues with the  network connection stability. So let’s talk to Goose + gpt-oss:20b +  linux-mcp-server about it. Here’s the initial prompt I used:

My Wifi doesn't work very well. It cuts out after a few minutes. Help me fix it. Can you find the error messages in the system logs and diagnose the problem?

It responded with the following:

I'll help you diagnose your WiFi connectivity issues by examining the system logs for error messages related to your network interfaces and wireless connectivity. Let me start by gathering information about your system and checking the relevant logs.

🤖 LLM output 🤖

I’ll help you diagnose your WiFi connectivity issues by examining the system logs for error messages related to your network interfaces and wireless connectivity. Let me start by gathering information about your system and checking the relevant logs.

It then made a series of tool calls, including Get System Information, Get Network Interfaces, Get Journal Logs, Get Hardware Information, Get Service Status service_name:NetworkManager, Get Service Status service_name:wpa_supplicant, Read Log File. The result was this analysis, which is the actual problem I was hoping it could find!

⚡ Problem Summary

Your ATH12K PCI (Qualcomm 802.11ax) wireless card repeatedly reports

 
ath12k_pci 0000:c2:00.0: failed to enqueue rx buf: -28

every few minutes, which triggers a drop of the wireless link. The driver is trying to enqueue an RX buffer for the hardware but fails with errno ‑28.

‑28

-ENOMEM

(out‑of‑memory for the driver buffer); the kernel cannot allocate a DMA‑coherent RX descriptor.

✅ Likely Root Causes

Cause Evidence / Typical Scenario Fix / Work‑around
Driver bug or missing patch The kernel’s ath12k driver has had a long‑running issue with RX ring management in older 5.15/5.4 series. Update the kernel or apply the latest patch from the

linux

tree (5.18+ or the

ath12k

backports).

Out‑of‑memory in the driver The error itself is “‑28” – a memory‑allocation failure inside the driver. Reduce the number of RX descriptors, or enable fast‑RX disabled mode (

modprobe ath12k_pci ath12k_pci_disable_fast_rx=1

).

Firmware mismatch / corruption Old firmware (

ath12k_hwgen

files) don’t match the driver version.

Reinstall firmware from your distro (

sudo apt‑install –reinstall linux‑firmware

) or copy the latest from kernel source.

System memory pressure If many big processes run, DMA‑coherent memory pool can be exhausted. Free RAM, close memory‑heavy apps, or add swap.
ACPI/PCIe power‑management quirk Some laptops throttle the Wi‑Fi device after idle, resetting the buffer queue. Add

pci_bus_reset = off

or set

ath12k_pci_disable_ps=1

in a modprobe conf.

Hardware issue (e.g., faulty PCIe slot or NIC) Persistent failure after multiple driver/kernel upgrades. Test on another machine/PCIe slot or replace the card.

🔎 Diagnostic Checklist

  1. Kernel & Driver Version
     
    uname -r
    modinfo ath12k_pci | grep ^version:
  2. Driver Parameters
     
    cat /sys/module/ath12k_pci/parameters/*

    – See if

    ath12k_pci_disable_fast_rx

    or similar is already set.

  3. Firmware Location
     
    ls /lib/firmware/ath12k/ath12k/ar9009/ | grep wlan0 | head

    – If the files are missing or older than the driver, copy newer ones from

    /lib/firmware

    of a newer kernel.

  4. Kernel Log Around the Error
     
    sudo dmesg --ctime | grep -A3 'ath12k_pci 0000:c2:00.0'

    – Observe if there are any other “-ENOMEM” or “resource exhaustion” messages.

  5. Memory Usage Stats
     
    free -h
    vmstat 1 5
  6. PCIe Latency / Link State
     
    sudo lspci -vvv -s c2:00.0 | grep -iE "link|latency"

🚀 Quick‑Fix Path (Try in this order)

Step Command What it does
1
 
sudo apt update && sudo apt upgrade linux-firmware
Refresh firmware to the latest distro version.
2
 
sudo apt upgrade linux-image-$(uname -r)
Apply latest kernel with patched ath12k driver (or switch to 5.18+ if still on 5.15).
3
 
echo "ath12k_pci ath12k_pci_disable_fast_rx=1" | sudo tee /etc/modprobe.d/ath12k.conf
Force the driver to use a more conservative RX scheme.
4 Reboot and monitor:

dmesg -T | grep ath12k_pci
Verify the error disappears.
5 Optional: test on another machine or use a USB‑WiFi dongle (USB 802.11ax / 802.11ac) as a temporary workaround. Ensure the issue is not hardware‑specific.

**Tip:** After reboot, you can also verify driver parameters:

cat /sys/module/ath12k_pci/parameters/ath12k_pci_disable_fast_rx

📺 Advanced Debugging (if basic fixes don’t help)

  1. Enable debug logs
     
    sudo bash -c 'echo 1 > /sys/module/ath12k_pci/parameters/debug'
    sudo dmesg -T | grep ath12k
  2. Check PCIe device state
     
    sudo lspci -vv -s c2:00.0
  3. Use
    ethtool

    on the Wi‑Fi interface

     
    sudo ethtool -S wlp4s0
  4. Look for firmware logs
     
    grep -i 'ath12k' /var/log/syslog

📌 Bottom Line

The “failed to enqueue rx buf: –28” is an internal driver allocation failure that typically follows one of two paths:

  1. The driver or firmware is out of date → upgrade kernel/firmware.
  2. The driver configuration is too aggressive for your system’s memory budget → tweak module parameters or free RAM.

If you're still stuck after following the quick‑fix path, it's worth capturing more detailed logs with the above diagnostic commands and sharing them. We can then cross‑reference the exact kernel version/driver commit to see if a known patch exists.

Feel free to let me know which step you’ve tried or if you encounter any new log messages, and we’ll dig deeper!


Not too bad an analysis and set of debugging steps! I’ll follow up in the comments and let you know if the solution works.

Where’d my disk space go, Fedora?

Trawling through `du` on the command line, converting the numbers in your head, sorting them – it can be tedious. We even have graphical tools like `baobab`, but it takes time to load in the results and explore the data. And sometimes you might have questions it can’t answer in terms of the risk of deleting a specific directory, or the age of a specific file. It’s easier to be sloppy and just let the disk fill up. But there comes a time where that is no longer an option.

You can ask the system using the linux-mcp-server to analyze your disk usage, give you a hitlist of the top space-eating places on the file system, and give you advice with a risk analysis of how to clean it up.

Here’s my prompt:

I need help analyzing disk usage on my system. Can you: 1. Show me the current disk usage across all filesystems using get_disk_usage
2. Use list_directories_by_size to show me the 10 largest directories (this will help identify where disk space is being consumed)
3. Check if there are any large log files consuming space using get_journal_logs or read_log_file
4. Review running processes with list_processes to see if any are consuming excessive resources or creating temporary files After gathering this information, help me identify potential space-saving opportunities and assess the safety of cleaning up specific directories. Please don't only examine top-level directories. I want you to go deep if needed to find out where the largest files are!

I ran this prompt on my Fedora 42 system using linux-mcp-server with Goose connected to locally-served gpt-oss:20b, and here’s the output I got:


🤖 LLM output 🤖

Disk‑space overview (as of Nov 24 2025 15:21)

Filesystem Size Used Avail Use % Mounted on
/dev/mapper/luks‑61cedb0e… 952.3 GB 548.9 GB 399.6 GB 57.9 % /
/dev/mapper/luks‑61cedb0e… 952.3 GB 548.9 GB 399.6 GB 57.9 % /home
/dev/nvme0n1p2 973.4 MB 462.8 MB 443.4 MB 51.1 % /boot
/dev/nvme0n1p1 598.8 MB 19.3 MB 579.6 MB 3.2 % /boot/efi

Overall usage is comfortably below 60 % of a 952 GB volume, so immediate capacity pressure isn’t a concern. The biggest contributors to disk space today are in the ~/. hierarchy.


1. Biggest directories on the system

Path (relative to the mount point) Size (≈) Notes
~/ – User home (2 mounts: /home + /) 1 TB total 57 % used; the bulk of the space is in ~/

| ~/duffy/.local/share | 238 GB | Containers sub-dir, followed by Trash (7GB) – typical podman/docker container images |
| ~/duffy/.local/share/containers | 238 GB | Container layers, images, root filesystems – the prime candidate for cleanup |
| ~/duffy/.local | 266 GB | share (237 GB) dominates it |
| ~/duffy/.local/share/containers (inside share) | 238 GB | Same as above – just a different view |
| ~/duffy/.local/lib | 13 GB | Likely a virtual‑environment library set |
| ~/duffy/.local/bin | 4 GB | Helper binaries |
| ~/duffy/.local/share/Trash | 7 GB | User‑deleted items still resident on disk |
| ~/duffy/.local/share/containers (nested) | 238 GB | Same as above; redundant listings from recursive depth‑1 scans |
| ~/duffy/.local/share (top‑level) | 238 GB | containers is the absolute largest item |

Take‑away – 75 % of the 238 GB live inside three nested directories:

  • ~/duffy/.local/share/containers (238 GB) → Rooted in Podman/Container‑Store
  • ~/duffy/.local/share (238 GB) → Same data exposed at a higher level
  • ~/duffy/.local/share/Trash (7 GB)

2. Possible space savers

Category Recommendation Rationale
Containers podman system prune -a (or docker system prune -a if Docker is in use) Removes unreferenced images, containers, and caches. This can reclaim 200–250 GB if most containers are outdated or no longer referenced.
Trash gio trash –empty The 7 GB in Trash is still taking physical space; simply emptying it will free that amount.
Large libs/binaries Check ~/duffy/.local/lib – 13 GB, and ~/duffy/.local/bin – 4 GB If these are not actively used by a project, consider uninstalling or moving them to a secondary, less‑frequented store.
Ramalama & UV 9 GB (ramalama), 8 GB (uv) Possibly temporary files or caches from development tools. Inspecting the contents of these directories (du -h) can reveal if they are still needed.
Other caches pnpm store prune, virtualenv or pip cache purge Development tool caches often accumulate; they’re usually safe to delete once you’re done with the current development sessions.
Logs The system journal shows normal activity, and syslog access is blocked by policy. Systemd journal stores are rotated automatically; no urgent action required.
Boot partitions Not relevant – they’re low‑usage (boot/efi only 3 % used). No action needed.

3. Disk‑IO perspective

  • Reads: 111.8 GB; Writes: 85.6 GB since boot (≈ 1.2 TB total).
  • If writes are high relative to free space, consider enabling a tmpfs overlay for temporary files or moving large data to a separate, faster SSD. But in this case, writes are not approaching the 399 GB free.

4. Suggested cleanup workflow

# 1. Empty Trash

gio trash --empty

# 2. Prune unused containers/images

podman system prune -a   # or docker system prune -a

# 3. Remove leftover caches

pnpm store prune         # if pnpm is installed
pip cache purge          # for Python
virtualenv --clean       # optional

# 4. Inspect large “RAM” directories manually if you need deeper cleanup

du -h --max-depth=1 ~/duffy/.local/share/containers

Tip: After each step run df -h /home or du -sh ~/duffy/.local/* to see the impact.


5. Safety checklist

Action Why it’s safe (or risk)
Emptying Trash Deletes only user‑deleted files; confirm you don’t need the content.
podman system prune -a Deletes container images, containers, and volumes that are not referenced by any running or stopped container. Verify with podman ps -a before pruning.
Removing lib/bin from .local Only safe if you’re sure those libraries/bin files aren’t part of a running application.
Caution with tmpfs or moving large directories If you move a directory on‑the‑fly, ensure no running application depends on that path.

Bottom line

  • Current free space: ≈ 400 GB on both / and /home.
  • Largest consumptions: User‑space under ~/duffy/.local/share/containers (≈ 238 GB).
  • Actionable clean‑ups: Empty Trash, prune unused container images, and review large libraries/binaries. This should reclaim over 200 GB and bring the usage from 57.9 % down to roughly 40‑45 % – plenty of headroom for the future.

Feel free to ask what next steps you’d like to dig into (e.g., detailed contents of the containers dir, specific application logs, or targeted pruning commands).


Upgrade planning

So you may have noticed a little detail above – the system is a Fedora 42 system… and Fedora 43’s been out a month now! 😅 So, time to upgrade.

This example shows where we have some tools missing from the set provided in the linux-mcp-server. We’re including it for two reasons:

  • So you can see how this works manually
    You can see that even when specific tools you might not need are available in the MCP server, you can have the response give you instructions on commands to run on your own, and copy/paste the command output back into your chat to get analysis alongside the data the system is able to pull via the MCP tool calls;
  • To encourage you to submit additional tools to our project!
    We would love your additions to the project! Here’s where to get started: https://github.com/rhel-lightspeed/linux-mcp-server/blob/main/docs/CONTRIBUTING.md

Here’s the prompt I started with, with the same Goose + gpt-oss:20b + linux-mcp-server combination:

You are a Linux system administrator assistant analyzing a Fedora system for upgrade readiness. TASK: Examine this Fedora 42 system and provide a comprehensive upgrade readiness report for Fedora 43. ANALYSIS CHECKLIST:
1. Check current Fedora version: cat /etc/fedora-release
2. Review system updates status: dnf check-update
3. Identify third-party repositories: dnf repolist
4. List installed packages from non-Fedora repos: dnf list installed | grep -v @fedora
5. Check for broken dependencies: dnf check
6. Review disk space on root partition: df -h /
7. Check for unsupported or deprecated packages
8. Identify custom kernel modules: lsmod | grep -v "^Module"
9. Review SELinux status: sestatus
10. Check for pending system updates: dnf upgrade --refresh --assumeno REPORT FORMAT: # Fedora 43 Upgrade Readiness Report ## Current System Status
- Fedora version: [version]
- Kernel: [kernel version]
- Updates status: [current/outdated] ## Potential Issues
[List blocking issues with HIGH/MEDIUM/LOW severity] ## Third-Party Software
[List non-Fedora packages that may need attention] ## Recommendations
[Specific pre-upgrade steps needed] ## Overall Readiness: [READY/NEEDS ATTENTION/NOT READY]
Run the necessary commands and provide this analysis. Be specific about any issues found and give actionable recommendations.

Now, right away the model came back to me to complain it doesn’t have access to `dnf`, `cat`, etc. And that’s expected here. What it did was give me a list of homework to run for it to complete the analysis… for example, `dnf check-update` and `cat /etc/fedora-release`. I had a little back and forth in Goose with the model where it would ask me to run a command and I’d copy the output into the context. This resulted, finally, in the following report:


🤖 LLM output 🤖

Fedora 43 Upgrade Readiness Report

Analyzed System – Fedora 42 (Kernel 6.17.7‑200.fc42.x86_64)
Date – 2025‑11‑24


1. Current System Status

Item Value
Fedora release 42 (Adams)
Kernel 6.17.7‑200.fc42.x86_64
Root filesystem 953 GB LUKS, 58 % used (411 GB free) – > 15 % free
/var /usr Same as root partition (mounted the same LUKS device)
SELinux enabled (policy targeted), currently permissive
System‑wide packages No held packages (dnf versionlock list empty)
System modules No modules held.

TL;DR – The base system is clean; the kernel is up‑to‑date for 42, there is ample disk space, and there are no version‑locked packages.


2. Third‑Party Repos & Packages

Repository Description Current dnf repolist status
rpm-fusion-free, rpm-fusion-nonfree, rpm-fusion-updates Widely used RPM‑Fusion components Enabled
google-cloud-cli Google Cloud SDK (RPM built for EL 10) Enabled
visual-studio-code Microsoft VS Code RPMs Enabled
command‑line‑assistant, google‑chrome, PyCharm, unsupported‑fedora‑packages, goose, leaktk Various Copr builds (mostly Fedora‑42 based) Enabled

What we need to verify

  1. Is a Fedora 43 build available for each of the non‑Fedora repos above?
  2. Does google-cloud-cli have a Fedora 43‑compatible package? (EL 10 build may not be usable).
  3. Are there any el10‑specific dependencies that could surface during the upgrade?
  4. Any custom kernel modules that will require re‑compilation against the 43 kernel.

3. Potential Issues & Severity

Issue Severity Why it matters Immediate Remedy
Non‑Fedora packages (e.g., google‑cloud‑cli) MEDIUM May contain packages built for EL 10; could conflict with Fedora 43 libs. Verify if a Fedora 43 build exists or plan to remove/re‑build it.
Third‑party repos without 43 builds MEDIUM dnf system-upgrade pulls all enabled repos; lacking 43 packages causes transaction failure. Disable such repos temporarily (dnf config-manager –set-disabled <repo>) or enable the 43 stream when available.
Custom kernel modules LOW Modules compiled against 42 kernel won’t load on 43; services may drop. Re‑compile or patch modules after upgrade.
Broken dependencies reported by dnf check HIGH Would block the upgrade transaction. Run sudo dnf check now; fix any reported issues.
Insufficient disk space HIGH Upgrade scripts need > 15 % free. Not an issue (58 % free).

Current High‑Risk Items – None detected yet.
Next Action – Confirm each third‑party repo has 43‑compatible packages and set SELinux to enforcing.


4. Recommendations (Pre‑Upgrade Checklist)

Step Command Purpose
Confirm 43‑stream packages `dnf list –available * grep <repo-id>`
Verify SELinux enforcement sestatus Should show enforcing.
Check for broken dependencies sudo dnf check No errors should appear.
Refresh all repos sudo dnf upgrade –refresh Pull latest metadata.
Dry‑run upgrade sudo dnf system-upgrade download –releasever=43 –allowerasing Detect any missing packages or conflicts.
Optional: Disable problematic repos sudo dnf config-manager –set-disabled <repo> Prevent upgrade crash if a repo has no 43 build.
Persist SELinux config sudo sed -i ‘s/SELINUX=permissive/SELINUX=enforcing/’ /etc/selinux/config Make enforcement permanent.

5. Post‑Upgrade Actions

  1. Reboot into the new kernel (dnf system-upgrade reboot).
  2. Re‑compile any custom kernel modules against the new kernel (yum install kernel-devel-$(uname -r) then rebuild modules).
  3. Re‑enable any disabled repos once the upgrade completes.
  4. Verify critical services (systemctl status <service>) and check logs.
  5. Run sudo dnf distro-sync to ensure all packages are the latest from Fedora 43.

6. Overall Readiness

Criteria Status Comment
Disk space Ready 58 % free
Package health Ready No held or broken packages
Third‑party repos Conditional Verify 43‑compatibility
Custom modules Pending Need to identify modules and re‑compile
Final verdict READY (after addressing above points)

Next step – Run the three verification commands below and share the output with me:

sudo dnf check
sudo dnf repolist
dnf list installed | grep -v @fedora

With those outputs I can pinpoint any remaining blockers and give you a final, ready‑to‑proceed plan.

Happy upgrading!

Flock 2026 CfP open now until Feb 2nd 2026

Apply now for the Flock to Fedora 2026 Call for Proposals (CfP) at cfp.fedoraproject.org. This year, the submission deadline for the Flock CfP is Monday, February 2nd, 2026.

Flock 2026 registration is open

Last month we announced that we’ll be convening again in Prague for Flock 2026 in June. Everyone interested in attending can head over to the Flock 2026 website and register today! For those of you who want to contribute to Flock by presenting your thoughts and ideas in front of your fellow contributors, we’ve got some inspiration for you in the form of updated proposal themes.

Flock 2026 proposal themes

This year’s proposal themes are inspired by Fedora’s four foundations:

  1. Freedom: The Open Frontier — This theme explores how Fedora pushes the boundaries of technological freedom. We invite proposals on FOSS approaches to Artificial Intelligence, the advancement of open hardware like RISC-V, the development of open standards, and the protection of data privacy. Sessions should focus on how our work in the Fedora Project creates a more free and collaborative technological world for everyone.
  2. Friends: Our Fedora Story — This theme celebrates the people and practices that make our community unique. We seek proposals that share stories of mentorship, successful team collaboration, and effective onboarding within Fedora. Collaboration is key to our success. Sessions about our partnerships with other FOSS communities should center on the mutual benefits and the positive impact these relationships have on the Fedora Project.
  3. Features: Engineering Fedora’s Core — As a contributor conference, this theme dives deep into the craft of building our distribution and other Fedora outputs. We welcome sessions on improvements to our infrastructure, release engineering processes, quality assurance, packaging, and community tooling. This is the place for technical talks that showcase our engineering excellence and the collaborative work that makes Fedora’s deliverables possible, from code to final artifact.
  4. First: Blueprint for the Future: Fedora Linux 45 & 46 — This theme focuses on the near-term innovations that will define the next generation of Linux. With the next few Fedora Linux releases serving as the foundation for RHEL 11 and EPEL 11, this is a critical time. We are looking for forward-looking technical talks on the changes, features, and architectural decisions in F45 and F46 that will shape the future of the operating system, from the community desktop to the core of the enterprise platforms.

These themes are here to help get you thinking about topics you’d like to present. If you have something you want to talk about that doesn’t quite fit neatly into these themes, but you feel it belongs at Flock, go ahead and submit anyways! The reviewers are open to alternative topics. They are on the look out for topics that Fedora contributors are interested in discussing.

Flock financial travel assistance available

Financial travel assistance applications are now open as well. When you go to register to attend on the Flock 2026 website, you should also see links on how to apply for travel assistance if you need it. Financial assistance will be open until March 8th (several weeks after CfP closes on Febuary 8th). This is to give those with accepted talks an opportunity to figure out if they’ll need travel assistance.

Fedora at Kirinyaga University – Docs workshop

Kirinyaga University students group photo

We did it again, Fedora at Kirinyaga university in Kenya. This time, we didn’t just introduce what open source is – we showed students how to participate and actually contribute in real time.

Many students had heard of open source before, but were not sure how to get started or where they could fit. We did it hands-on and began with a simple explanation of what open source is: people around the world working together to create tools, share knowledge, and support each other. Fedora is one of these communities. It is open, friendly, and built by different people with different skills.

We talked about the many ways someone can contribute, even without deep technical experience. Documentation, writing guides, design work, translation, testing software, and helping new contributors are all important roles in Fedora. Students learned that open source is not only for “experts.” It is also for learners. It is a place to grow.

Hands-on Documentation Workshop

A room full of kirinyaga students on a worskhop

After the introduction, we moved into a hands-on workshop. We opened Fedora Docs and explored how documentation is structured. Students learned how to find issues, read contribution instructions, and make changes step-by-step. We walked together through:

  • Opening or choosing an issue to work on
  • Editing documentation files
  • Making a pull request (PR)
  • Writing a clear contribution message

By the end of the workshop, students had created actual contributions that went to the Fedora project. This moment was important. It showed them that contributing is not something you wait to do “someday.” You can do it today.

“This weekend’s Open Source Event with Fedora, hosted by the Computer Society Of Kirinyaga, was truly inspiring! 💻

Through the guidance of Cornelius Emase, I was able to make my first pull request to the Fedora Project Docs – my first ever contribution to the open-source world. 🌍
– Student at Kirinyaga University

Thank you note

Huge appreciation to:

  • Jona Azizaj — for steady guidance and mentorship.
  • Mat H. — for backing the vision of regional community building.
  • Fedora Mindshare Team — for supporting community growth here in Kenya.
  • Computer Society of Kirinyaga — for hosting and bringing real energy into the room.

And to everyone who played a part – even if your name isn’t listed here, I see you. You made this possible.

Growing the next generation

The students showed interest, curiosity, and energy. Many asked how they can continue contributing and how to connect with the wider Fedora community. I guided them to Fedora Docs, Matrix community chat rooms, and how they can be part of the Fedora local meetups here in Kenya.

We are introducing open source step-by-step in Kenya. There is a new generation of students who want to be part of global technology work. They want to learn, collaborate, and build. Our role is to open the door and walk together(I have a discourse post on this, you’re welcome to add your views).

A group photo of students after the workshop

What Comes Next

This event is part of a growing movement to strengthen Fedora’s presence in Kenya. More events will follow so that learning and contributing can continue.

We believe that open source becomes strong when more people are included. Fedora is a place where students in Kenya can learn, grow, share, and contribute to something global.

We already had a Discourse thread running for this event – from the first announcement, planning, and budget proposal, all the way to the final workshop. Everything happened in the open. Students who attended have already shared reflections there, and anyone who wants to keep contributing or stay connected can join the conversation.

You can check the events photos submitted here on Google photos(sorry that’s not FOSS:))

Cornelius Emase,
Your Friend in Open Source(Open Source Freedom Fighter)

Announcing Flock to Fedora 2026 (14-16 June): Join Us in Prague!

Banner image for the Flock to Fedora 2026 conference. The image shows Colúr, the animated mascot of Flock, holding a megaphone. The "Flock" logo appears with "Prague, Czech Republic" and "June 14 - 16, 2026" written below the Flock logo.

The official dates and location are set for Flock to Fedora 2026, the premier annual conference for Fedora Project contributors. The event will take place from 14-16 June 2026, in Prague, Czechia.

For Flock 2026, we are returning to the Vienna House by Wyndham Andel’s Prague, located at:

Stroupeznickeho 21
Prague, 150 00
Czech Republic

While all three days will be full conference days, the arrangement of the schedule will change slightly in 2026. Sunday, 14 June, will be designated as Day 0, featuring workshops, team meetups, and hands-on contributor sessions. The main conference activities, including streamed content, the opening keynote, and other sessions, are scheduled for Monday, 15 June, and Tuesday, 16 June.

Coordinated Scheduling with DevConf CZ

Following community feedback from last year, Flock 2026 has been scheduled to align more closely with DevConf.CZ. The conference will conclude just before DevConf.CZ begins in Brno (18-20 June 2026). This compressed travel schedule is intended to make it easier for community members who wish to attend both events.

Call for Proposals & Conference Themes

The Call for Proposals (CFP) for Flock 2026 will open in early December 2025 and close shortly after FOSDEM 2026 (31 January – 1 February). Speaker confirmations are scheduled to be sent in March 2026.

For Flock 2026, we are taking a more focused approach to session content. The Fedora Council, FESCo, and the Mindshare Committee are shaping key themes for the CFP. All presentation and workshop submissions should align with one of these themes. More details will be shared when the CFP opens.

Planning for Flock 2026

Here is what you need to know to plan your attendance:

  • Registration: Conference registration is scheduled to open in January 2026.
  • Sponsorship: Is your company or organization interested in sponsoring Flock 2026? Our sponsorship prospectus for Flock 2026 is now available on the Flock 2026 website. Organizations interested in supporting Flock and the Fedora community are encouraged to review the prospectus and contact the organizing team with any questions.
  • Hotel Block: A discounted block of rooms is arranged at the conference hotel. More information about the discounted hotel block can be found on the Flock website.
  • Travel Day & Connections: 17 June is designated as a free travel day between Flock to Fedora 2026 and DevConf.CZ. Frequent bus and train connections are available for travel between Prague and Brno.
  • Sponsored Travel: We intend to offer sponsored travel again for Flock to Fedora 2026. More details will follow in December 2025.

Get Involved & Ask Questions

The official Flock to Fedora 2026 Matrix room, #flock:fedoraproject.org, is the best place to connect with organizers and other community members. We encourage you to join the channel for the latest updates and to ask any questions you may have.

Flock to Fedora 2026 web site

A Note on Our Flock to Fedora 2026 & 2027 Plans

We recognize that returning to the same city and venue for a second consecutive year is a departure from Flock’s tradition. This decision was made intentionally with two key goals in mind.

First, by working with a familiar venue, our organizing team can optimize its processes and plan further in advance. This stability for Flock to Fedora 2026 will give us more opportunity to improve our internal processes and explore new ways to incorporate community input into the design of Fedora’s flagship contributor conference.

Second, this allows us to plan for a significant change in 2027. The Flock organizing team is committed to exploring new locations for Flock 2027, with a particular focus on regions outside of North America and Europe. We acknowledge the travel difficulties many of our contributors in regions like LATAM and APAC face. We learned valuable lessons from past planning cycles and are eager to achieve this goal, while also recognizing that unforeseen circumstances can impact our plans. We will work with community members in these regions to explore possible options and conduct thorough research on pricing and availability for 2027.

We look forward to seeing you in Prague for Flock 2026, 14-16 June.

How to rebase to Fedora Linux 43 on Silverblue

Fedora Silverblue is an operating system for your desktop built on Fedora Linux. It’s excellent for daily use, development, and container-based workflows. It offers numerous advantages such as being able to roll back in case of any problems. If you want to rebase to Fedora Linux 43 on your Fedora Silverblue system, this article tells you how. It not only shows you what to do, but also how to revert things if something unforeseen happens.

Update your existing system

Prior to actually doing the rebase to Fedora Linux 43, you should apply any pending updates. Enter the following in the terminal:

$ rpm-ostree update

or install updates through GNOME Software and reboot.

Note

rpm-ostree is the underlying atomic technology that all the Fedora Atomic Desktops use. The techniques described here for Silverblue will apply to all of them with proper modifications for the appropriate desktop.

Rebasing using GNOME Software

GNOME Software shows you that there is new version of Fedora Linux available on the Updates screen.

First thing to do is download the new image, so select the Download button. This will take some time. When it is done you will see that the update is ready to install.

Select the Restart & Upgrade button. This step will take only a few moments and the computer will restart when the update has completed. After the restart you will end up in a new and shiny release of Fedora Linux 43. Easy, isn’t it?

Rebasing using terminal

If you prefer to do everything in a terminal, then this part of the guide is for you.

Rebasing to Fedora Linux 43 using the terminal is easy. First, check if the 43 branch is available:

$ ostree remote refs fedora

You should see the following in the output:

fedora:fedora/43/x86_64/silverblue

If you want to pin the current deployment (meaning that this deployment will stay as an option in GRUB until you remove it), you can do this by running this command:

# 0 is entry position in rpm-ostree status
$ sudo ostree admin pin 0

To remove the pinned deployment use the following command:

# 2 is entry position in rpm-ostree status 
$ sudo ostree admin pin --unpin 2

Next, rebase your system to the Fedora Linux 43 branch.

$ rpm-ostree rebase fedora:fedora/43/x86_64/silverblue

Finally, the last thing to do is restart your computer and boot to Fedora Linux 43.

How to roll back

If anything bad happens (for instance, if you can’t boot to Fedora Linux 43 at all) it’s easy to go back. At boot time, pick the entry in the GRUB menu for the version prior to Fedora Linux 43 and your system will start in that previous version rather than Fedora Linux 43. If you don’t see the GRUB menu, try to press ESC during boot. To make the change to the previous version permanent, use the following command:

$ rpm-ostree rollback

That’s it. Now you know how to rebase Fedora Silverblue to Fedora Linux 43 and roll back. So why not do it today?

Known Issues

FAQ

Because there are similar questions in comments for each blog about rebasing to newer version of Silverblue I will try to answer them in this section.

Question: Can I skip versions during rebase of Fedora? For example from Fedora 40 Silverblue to Fedora 43 Silverblue?

Answer: Although it could sometimes be possible to skip versions during rebase, it is not recommended. You should always update to one version above (40->41->42->43 for example) to avoid unnecessary errors.

Question: I have rpm-fusion layered and I get errors during rebase. How should I do the rebase?

Answer: If you have rpm-fusion layered on your Silverblue installation, you should do the following before rebase:

$ rpm-ostree update --uninstall rpmfusion-free-release --uninstall rpmfusion-nonfree-release --install rpmfusion-free-release --install rpmfusion-nonfree-release

After doing this you can follow the guide in this blog post.

Question: Could this guide be used for other ostree editions (Fedora Atomic Desktops) as well like Kinoite, Sericea (Sway Atomic), Onyx (Budgie Atomic),…?

Yes, you can follow the Rebasing using the terminal part of this guide for every Fedora Atomic Desktop. Just use the corresponding branch. For example, for Kinoite use fedora:fedora/43/x86_64/kinoite

Fedora Linux 43 is here!

I’m excited to announce my very first Fedora Linux release as the new Fedora Project Leader. Fedora Linux 43 is here! 43 releases! Wow that’s a lot. I was thinking about proposing special tetracontakaitrigon stickers to celebrate this release, but I’m not sure anyone would notice they weren’t circles.

Thank you and congrats to everyone who has contributed to Fedora to this release, and in all the releases leading up to this one. I’m grateful to be back with a chance to take stewardship of the collaboration as the Fedora Project leader. I’ve been getting my feet under me as much as I can in these first few months. I’m looking forward to writing up some longer missives about where I want to steer this ship, but for right now I just want to highlight some of the changes you should expect to encounter in the latest release of Fedora Linux. Read the highlights below to find out more. Or if you are ready just jump right in!

Upgrade

If you have an existing system, Upgrading Fedora Linux to a New Release is easy. In most cases, it’s not very different from just rebooting for regular updates, except you’ll have a little more time to grab a coffee.

Fresh Install

If this is your first time running Fedora Linux, or if you just want to start fresh with Fedora, download the install media for our flagship Editions (Workstation, KDE Plasma Desktop, Cloud, Server, CoreOS, IoT),  for one of our Atomic Desktops (Silverblue, Kinoite, Cosmic, Budgie, Sway), or for alternate desktop options (like Cinnamon, Xfce, Sway, or others).

What’s new?

As usual, with Fedora, there are just too many individual changes and improvements to go over in detail. You’ll want to take a look at the release notes for that.

Notable User Visible Changes

There are, however, a few notable user visible changes in this release. For those of you installing fresh Fedora Linux 43 Spins, you may be greeted with the new Anaconda WebUI. This was the default installer interface for Fedora Workstation 42, and now it’s the default installer UI for the Spins as well.

If you are a GNOME desktop user, you’ll also notice that the GNOME is now Wayland-only in Fedora Linux 43. GNOME upstream has deprecated X11 support, and has disabled it as a compile time default in GNOME 49. Upstream GNOME plans to fully remove X11 support in GNOME 50.

Plumbing Upgrades

Beyond the user-visible changes, there are a couple of significant bits of plumbing that should go unnoticed for most users but are a big deal, nonetheless.

Fedora Linux 43 will be the first release with RPM 6.0. Like I said, this should go unnoticed to end-users, but it is a significant change. RPM 6.0 provides some interesting security enhancements, like multiple key signing of packages. This should help future-proof package signing as we transition to post-quantum-crypto OpenPGP keys in future releases.

We’re also moving forward with our bootc enablement story. Fedora CoreOS is now buildable from a Fedora base bootc image using a Containerfile, instead of needing to be composed with a custom tool. That means anyone with podman can build the Fedora CoreOS image, whether manually or via CI/CD automation.

Fedora CoreOS (FCOS) is also changing how it’s issuing updates to users in Fedora 43. Instead of using an OSTree repository, FCOS updates will be delivered exclusively as OCI images. FCOS 42 provided both OSTree repository and OCI registry as a transition for users. In FCOS 43, the OSTree updates are disabled entirely.

Save the Date: Fedora Linux 43 Release Party!

To celebrate all this incredible community work, we’ll be hosting a virtual Fedora Linux 43 Release Party! Please save the date for Friday, 21 November. We’re still finalizing the schedule and speakers, so registration isn’t open just yet, but more details will be shared soon. You can keep an eye on the Fedora Linux 43 Release Party Schedule wiki page for the latest updates!
