This article series takes a closer look at interesting projects that recently landed in Copr.
Copr is a build-system for anyone in the Fedora community. It hosts thousands of projects with a wide variety of purposes, targeting diverse groups of users. Some of them should never be installed by anyone, some are already transitioning into the official Fedora repositories, and others fall somewhere in between. Copr allows you to install third-party software not found in the standard Fedora repositories, try nightly versions of your dependencies, use patched builds of your favourite tools to support some non-standard use-cases, and experiment freely.
Vicinae is a fast application launcher written in C++/QT. Inspired by tool Raycast, it provides instant app and file search and clipboard history.

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.
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!
The “failed to enqueue rx buf: –28” is an internal driver allocation failure that typically follows one of two paths:
The driver or firmware is out of date → upgrade kernel/firmware.
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:

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).
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;
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
sudo sed -i ‘s/SELINUX=permissive/SELINUX=enforcing/’ /etc/selinux/config
Make enforcement permanent.
5. Post‑Upgrade Actions
Reboot into the new kernel (dnf system-upgrade reboot).
Re‑compile any custom kernel modules against the new kernel (yum install kernel-devel-$(uname -r) then rebuild modules).
Re‑enable any disabled repos once the upgrade completes.
Verify critical services (systemctl status <service>) and check logs.
Run sudo dnf distro-sync to ensure all packages are the latest from Fedora 43.

With those outputs I can pinpoint any remaining blockers and give you a final, ready‑to‑proceed plan.
Happy upgrading!
Give it a try, let us know what you think!

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:
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.
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.
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.
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.

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
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.
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).
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)
The Fedora community is coming together once again to celebrate the release of Fedora Linux 43, and you’re invited! Join us on Friday, November 21, 2025, from 13:00 to 16:00 UTC on Matrix for our virtual Fedora 43 Release Party.
This is our chance to celebrate the latest release, hear from contributors across the project, and see what’s new in Fedora Workstation, KDE, Atomic Desktops, and more. Whether you’re a long-time Fedora user or new to the community, it’s the perfect way to connect with the broader community, learn more about Fedora, and hang out in Matrix chat with your Fedora friends.
We have a lineup of talks and updates from across the Fedora ecosystem, including updates directly from teams who have been working on changes in this release. We’ll kick things off with Fedora Project Leader Jef Spaleta and Fedora Community Architect Justin Wheeler, followed by sessions with community members like Timothée Ravier on Atomic Desktops, Peter Boy and Petr Bokoč on the new Fedora Docs initiative, and Neal Gompa and Michel Lind discussing the Wayland-only GNOME experience. You’ll also hear from teams across Fedora sharing insights, demos, and what’s next for the project.
Registration is free but required to join the Matrix event room. Once registered, you’ll receive an invitation in your Matrix account before the event begins.
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?
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:
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
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.
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!

Below are a few noteworthy changes in the latest release of Fedora Workstation that we think you will love. Upgrade today from the official website, or upgrade your existing install using GNOME Software or through the terminal with dnf system-upgrade.
GNOME 49
Fedora Linux 43 Workstation also ships with the brand-new GNOME 49 release, bringing a host of refinements to your desktop. This update introduces significant enhancements for multiple display setups, an improved and streamlined workflow for taking screenshots and screen recordings, and a new “Focus Mode” to help you minimize distractions. Under the hood, resource-smart background throttling improves performance and battery life, while the Settings app has been polished with a refined UI. These are just the highlights. Check out the official GNOME 49 release notes to find more information about all the new features.
Wayland-only GNOME
One significant change we want to forewarn you about is that Fedora Linux 43 is removing the GNOME X11 packages from the Fedora repositories. All users of the GNOME X11 session will be migrated to the GNOME Wayland session with the upgrade to Fedora Workstation 43.
The transition to the GNOME Wayland session in Fedora Workstation 43 has been in the works for nearly a decade. There have been several prior steps toward this goal, such as the work in Fedora Linux 41 to remove legacy X11 dependencies from core media components.
Wayland has been the default GNOME session on Fedora Workstation for many years, but this release completes the change. The legacy gnome-session-xsession packages have been removed from the Fedora Linux 43 repositories.
This change will unlock a new level of performance and hardware compatibility. You’ll immediately notice smoother, cleaner visuals thanks to triple buffering, which dramatically reduces screen tearing. This change also improves support for a range of hardware, including enhanced drivers for Intel Xe graphics and improvements for systems using NVIDIA Optimus and Hybrid Mode.
A new default video player — Showtime
The default video player has been changed from Totem to Showtime. Showtime is built on the newer GTK 4 and Libadwaita libraries.
Use COLR for Noto Color Emoji
The Noto Color Emoji fonts have released some new files with the COLRv1 format. The COLRv1 format is a color scalable font compared with the previous color bitmap fonts. This new scalable font format should have better or similar rendering results compared to the old bitmap font format. See the change notes for more details.
Peas 2.0
If you are an app developer, you might be interested in the upgrade to Peas 2. Peas is a gobject-based plugins engine that is used by several GNOME applications.
Fedora test days are events where anyone can help make certain that changes in Fedora work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. If you’ve never contributed to Fedora before, this is a perfect way to get started.
There are three test days occurring in the next two weeks covering three topics:
Tuesday October 03, is to test the Fedora Cloud
Thursday October 05 , is to test the Fedora Upgrade
Monday October 09 , is to test Virtualization
Come and test with us to make Fedora 39 even better. Read more below on how to do it.
Fedora Cloud test day
Fedora Linux 39 is coming close to the release date and the Fedora Cloud SIG would like to get the community together to find and squash some bugs.
The test day will occur on Tuesday October 03. This event will test Fedora Cloud Base content. See the wiki page for links to the Beta Cloud Base Images. We have qcow, AMI, and ISO images ready for testing.
Upgrade test day
As we come closer to Fedora Linux 39 release dates, it’s time to test upgrades. This release has a lot of changes and it becomes essential that we test the graphical upgrade methods as well as the command line methods.
This test day will happen on Thursday, October 05. It will test upgrading from a full updated F37 and F38 to F39 for all architectures (x86_64, ARM, aarch64) and variants (WS, cloud, server, silverblue, IoT). See this wiki page for information and details.
Virtualization test day
This test day will happen on Monday, October 09 and will test all forms of virtualization possible in Fedora. The test day will focus on testing Fedora or your favorite distro inside a bare metal implementation of Fedora running Boxes, KVM, VirtualBox and whatever you have. The general features of installing the OS and working with it are outlined in the test cases which you will find on the results page.
How do test days work?
A test day is an event where anyone can help make certain that changes in Fedora work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. Test days are the perfect way to start contributing if you not in the past.
The only requirement to get started is the ability to download test materials (which include some large files) and then read and follow directions step by step.
Detailed information about all the test days are on the wiki page links provided above. If you are available on or around the days of the events, please do some testing and report your results.
