Fedora Asahi Remix 44 is now available

We are happy to announce the general availability of Fedora Asahi Remix 44. This release brings Fedora Linux 44 to Apple Silicon Macs.

Fedora Asahi Remix is developed in close collaboration with the Fedora Asahi SIG and the Asahi Linux project. This release incorporates all of the exciting improvements brought by Fedora Linux 44.  Fedora Asahi Remix 44 also retires our vendored Mesa and virglrenderer packages. Users who have not already manually done so will be automatically transitioned to the upstream Mesa and virglrenderer packages provided by the upstream Fedora repositories.

Fedora Asahi Remix offers KDE Plasma 6.6 as our flagship desktop experience, with all of the new and exciting features brought by Fedora KDE Plasma Desktop 44.  Plasma Setup replaces the previous Calamares-based setup wizard, providing a Plasma-native experience for user account creation and system setup. Additionally, Plasma Login Manager is now the default greeter and session manager, replacing SDDM. This applies to new installs only; users upgrading from previous versions of Fedora Asahi Remix will not have their configuration changed.

A GNOME variant is also available, featuring GNOME 50, with both desktop variants matching what Fedora Linux offers. Fedora Asahi Remix also provides a Fedora Server variant for server workloads and other types of headless deployments. Finally, we offer a Minimal image for users that wish to build their own experience from the ground up.

You can install Fedora Asahi Remix today by following our installation guide. Existing systems running Fedora Asahi Remix 42 or 43 can be updated following the usual Fedora upgrade process. Upgrades via GNOME’s Software application are unfortunately not supported; either KDE’s Plasma Discover or DNF’s System Upgrade command must be used.

Please report any Remix-specific issues in our tracker, or reach out in our Discourse forum or our Matrix room for user support.

What’s New in Fedora KDE Plasma Desktop 44

Fedora has released Fedora KDE Plasma Desktop Edition 44 to the public.

The Fedora KDE Plasma Desktop Edition is suitable for many needs.  It combines the reliable and trusted Fedora Linux base with the KDE Plasma Desktop environment.  It provides a selection of KDE applications that are simple by default, but powerful when needed.

KDE Plasma 6.6

The KDE community makes your life easier with the latest release of KDE Plasma. It builds upon the foundations of Plasma 6 to provide a seamless, friendly, and familiar experience.

Fedora KDE 44 ships with Plasma 6.6.4 featuring:

  • Custom global theme creation by saving the current theme setup
  • More options for using color accent in windows with tint intensity for window frames
  • Support for connecting to Wi-Fi networks by scanning QR codes
  • Per-application volume adjustment from the task manager
  • New grayscale filter for colorblindness correction
  • New screen magnifier feature that tracks the mouse pointer
  • New “Slow keys” and “reduced motion” settings
  • Spectacle can do OCR scanning of images to capture text
  • Per-window filter from screencast through the menu in the title bar

There’s so much more detail available in the Plasma 6.6 release announcement.

Fedora KDE 44 specific updates

Beyond just the updates included in KDE Plasma 6.6, there are some major new features with Fedora KDE on Fedora Linux 44.

  • Fresh installations now use the brand-new Plasma Setup and Plasma Login Manager. These provide a more cohesive and integrated experience from the moment the computer is powered on the first time. The installation process has been simplified. It now enables you to easily set up a computer with Fedora KDE Plasma Desktop for a friend or a loved one.
  • The on-screen keyboard uses the new Plasma Keyboard, providing a fresh and future-forward implementation for keyboard input.

Fedora Linux 44 general updates

Some broader changes in Fedora Linux also directly impact Fedora KDE Plasma Desktop Edition, notably:

  • PackageKit now uses version 5 of the DNF package manager as the backend.
  • Support for select Qualcomm-based laptops.
  • The /etc/pki/tls/cert.pem file no longer exists by default. This may impact some programs that expect this file to provide system CA certificates instead of leveraging behaviors built into cryptographic security libraries to offer this information.

Fedora Ready is ready for Fedora KDE

The Fedora KDE Plasma Desktop 44 edition is fully supported within the Fedora Ready program. Fedora KDE is actively engaging with hardware vendors to support Fedora KDE Plasma Desktop on their devices.

We are pleased to announce that Star Labs offers preinstalled Fedora KDE Plasma Desktop as an option for their portfolio of devices. As makers of computers with an open source ethos embedded into the core of their products with even open source firmware powered by Coreboot, they share many of the same principles the Fedora community values. This is a very exciting moment for Fedora KDE and we look forward to deepening our collaboration with Fedora Ready participants and extending to other vendors. If you are a vendor potentially interested in Fedora Ready, please reach out!

Wrap-up

The Fedora KDE SIG hopes that you’ll find the Fedora KDE Plasma Desktop 44 to be a wonderful experience. When you’re ready to try it, click here for download links and verification instructions. If you’d like to learn more, check out the Fedora KDE Plasma Desktop website.

Sealed Fedora Atomic Desktop bootable container images

I’m happy to announce that we have sealed bootable container images ready for testing for the Fedora Atomic Desktops!

What are sealed bootable container images?

Sealed bootable container images include all the components needed to create a fully verified boot chain, from the firmware to the operating system composefs image. This relies on Secure Boot and thus only supports system booting with UEFI on x86_64 & aarch64.

The components are:

  • systemd-boot as bootloader
  • a Unified Kernel Image (UKI) which includes the Linux kernel, an initrd and the kernel command line
  • a composefs repository with fs-verity enabled. This is managed by bootc.

Both systemd-boot and the UKI are signed for Secure Boot. The images are test images so the components are not signed with the official keys from Fedora.

The main direct benefit that we will get from this support is that we will be able to enable passwordless disk unlocking using the TPM in a way that will be reasonably secure by default.

How do I test those images?

See the instructions at github.com/travier/fedora-atomic-desktops-sealed on how to give the pre-built container and disk images a try and how to build your own.

We welcome testing and feedback! Please see the list of known issues and report new issue at github.com/travier/fedora-atomic-desktops-sealed. We’ll redirect them as needed to the right upstream projects.

Beware, those are testing images. The root account does not have a password set and sshd is enabled, by default, to make debugging easier. The UKI and systemd-boot are signed for Secure Boot but, since those are test images, they are not signed with the official keys from Fedora. Don’t use those images in production.

Where can I get more details about how this works?

If you want to know more about how sealed images work (i.e. how we make bootable containers, UKI and composefs work together to create a verified boot chain), see the following presentations and documentation:

Thanks to all the contributors that made this possible, notably (but non exhaustively) from the following projects: bootc & bcvk, composefs & composefs-rs, chunkah, podman & buildah and systemd.

What’s New for Fedora Atomic Desktops in Fedora Linux 44

Fedora Linux 44 has been released! 🎉 So, let’s see what is included in this new release for the Fedora Atomic Desktop variants (Silverblue, Kinoite, Sway Atomic, Budgie Atomic and COSMIC Atomic).

Changes for all Atomic Desktops

Issue tracker moved to the new Fedora forge

We have moved the cross-variants issue tracker to the new Fedora forge. This is the best place to file issues that impacts all variants or to coordinate work between all of them. If you have issues specific to a given desktop environment then we usually prefer to track them in each respective SIG trackers. These are available on the README for the atomic-desktops organization.

Unified documentation, hosted on the new forge

The unified documentation for all Atomic Desktops is finally live! Unfortunately the translations have not been migrated so we will need help to re-translate everything again, once the translation setup is ready with the new forge. It should be mostly copy/paste from the previous docs and this time we will only have to translate the docs once and not for every (new) variant.

See the tracking issue atomic-desktops#10.

Removal of FUSE version 2 libraries

FUSE version 2 has been deprecated and unmaintained for a while so we have removed it from the images. In practice, this means two things:

  • If you are using AppImages, some of them may not work anymore.
  • If you are using legacy backends with Plasma Vault on Kinoite, you need to migrate your data.

See the Fedora Change and the tracking issue atomic-desktops#50. The implications are detailed below.

AppImages and the FUSE 2 libraries

Some AppImages are still using an old AppImage runtime that relies on FUSE 2 libraries being available on the host. See the Discussion thread for examples on how to check the runtime of an AppImage.

If some of your AppImages do not work on Fedora Atomic Desktops 44, we recommend:

  • Looking for a Flatpak for the application and giving it another try. Consider helping upstream package their application as a Flatpak.
  • Reporting the issue upstream so that they are aware that they should use a newer runtime. Consider helping upstream with this as well.

EncFS or CryFS backends for Plasma Vaults are removed

KDE upstream no longer recommends using the EncFS nor CryFS backends for Plasma Vaults, notably because they rely on the FUSE 2 libraries. If you are using one of those backends, you should migrate your data to a new vault using the only maintained backend (gocryptfs). Ideally this should occur before the update to Fedora Linux 44. If you have already updated to Fedora Linux 44 and need access to your data, you can layer the needed packages (cryfs or fuse-encfs) using rpm-ostree install <package>, then migrate your data and finally reset the layers with rpm-ostree reset.

Dropping compatibility for pkla Polkit rules

Support for the legacy pkla Polkit rules format has been removed. It is unlikely that you were relying on support for those rules as most of the ecosystem has moved on to the new JavaScript based format.

See the Fedora Change and the tracking issue atomic-desktops#102.

What’s New in Silverblue

GNOME 50

Fedora Silverblue comes with the latest GNOME 50 release. For more details about the changes that occur alongside GNOME 50, see What’s New in Fedora Workstation 44 on the Fedora Magazine.

What’s New in Kinoite

KDE Plasma 6.6

Fedora Kinoite ships with Plasma 6.6, Frameworks 6.24 and Gear 25.12.

See also What’s New in Fedora KDE Plasma Desktop 44 in the Fedora Magazine.

KDE Plasma Login Manager replaces SDDM

The brand new Plasma Login Manager replaces SDDM to provide a more integrated experience with systemd and the KDE Plasma session.

See the Fedora Change.

Unified out of the box experience with KDE Plasma Setup (OEM installation)

Thanks to the new Plasma Setup, it is now possible to install the system with Anaconda with minimal configuration and then complete the installation on the first boot by creating a new user and selecting the timezone. This is great when you want to install Fedora Kinoite on a computer and don’t want to setup a user in advance.

See the Fedora Change.

What’s New in Sway Atomic

Nothing specific for this release.

What’s New in Budgie Atomic

Fedora Budgie Atomic comes with the latest 10.10.2 Budgie release. This release brings Wayland support to Budgie Atomic. See the 10.10 release announcement for more details.

What’s New in COSMIC Atomic

Fedora COSMIC Atomic comes with the latest 1.0.8 release of the COSMIC desktop. This is now considered stable.

Universal Blue, Bluefin, Bazzite and Aurora

Our friends in the Universal Blue project (Bazzite, Bluefin, Aurora) have prepared the update to Fedora Linux 44. Look for upcoming announcements in their Discourse.

As always, I heavily recommend checking them out, especially if you feel like some things are missing from the Fedora Atomic Desktops and you depend on them (NVIDIA drivers, extra media codec, out of tree kernel drivers, etc.).

What’s Next

Helping us with a few nasty bugs

If you have an interest in contributing to Fedora Atomic Desktops, here are some bugs that we will have to fix in the short term. We would greatly appreciate help with:

  • Fixing root mount options (atomic-desktops#72): This is a long standing and mostly invisible bug that impacts performance.
  • Moving away from nss-altfiles (atomic-desktops#108): This is another long standing source of issues that new users regularly face.

Sealed Fedora Atomic Desktop bootable container images

Sealed images are now ready for testing! See the other article for all the details.

Road map to Bootable Containers

A lot of work is happening to make the transition to Bootable Containers as smooth as possible for our existing users. You can look at the road map for this transition at atomic-desktops#26.

One of the tasks is to move away from our unmaintained installation ISO building scripts to the new image-builder tooling. This is planned for Fedora Linux 45 for the ostree variants and support for Bootable Container will follow right after.

Another task is to start building the Fedora Atomic Desktops Bootable Container images using the Fedora Konflux instance.

Where to reach us

We are looking for contributors to help us make the Fedora Atomic Desktops the best experience for Fedora users.

How to Rebase to Fedora Linux 44 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 44 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 44, 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 44. 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 44 using the terminal is easy. First, check if the 44 branch is available:

$ ostree remote refs fedora

You should see the following in the output:

fedora:fedora/44/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 44 branch.

$ rpm-ostree rebase fedora:fedora/44/x86_64/silverblue

Finally, the last thing to do is restart your computer and boot to Fedora Linux 44.

How to roll back

If anything bad happens (for instance, if you can’t boot to Fedora Linux 44 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 44 and your system will start in that previous version rather than Fedora Linux 44. 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 44 and roll back. So why not do it today?

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 a rebase of Fedora Linux? For example from Fedora Silverblue 41 to Fedora Silverblue 44?

Answer: Although it could sometimes be possible to skip versions during rebase, it is not recommended. You should always update to one version prior (41->42->43->44 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/44/x86_64/kinoite

The Fedora Linux 44 Release is Here!

I’m excited to announce that Fedora Linux 44 is here! Keep reading to discover highlights of Fedora Linux 44, or if you are ready, just jump right in and give Fedora Linux 44 a try!

Thanks to everyone who helped!

Thank you and congrats to everyone who has contributed to this release. And thanks to everyone who showed up for the virtual release party last Friday. We celebrated a little early this year, just after the go/no-go meeting made the release official. If you weren’t able to join us live, you can watch the recording and hear about some of the great work from the contributors involved.

Looking to 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.

Ready to 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), or one of our Atomic Desktops (Silverblue, Kinoite, Cosmic, Budgie, Sway), or alternate desktop options (like Cinnamon, Xfce, Sway, or others).

What’s new?

As usual with Fedora Linux, 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

Anaconda

For those of you installing fresh Fedora Linux 44 Spins, you may notice a change in how Anaconda handles network devices. Anaconda now only creates network profiles for devices configured during installation (by boot options, kickstart, or interactively in UI) instead of providing default profiles for all devices. This change will simplify post-installation network configuration for users who need to customize after installation.

Workstation

Fedora Linux 44 Workstation ships with the latest GNOME release, GNOME 50. This comes with a long list of refinements to your desktop, including everything from accessibility to color management and remote desktop. Many of the applications that are installed by default on Fedora Workstation have also seen improvements, from Document Viewer to File Manager and Calendar. To learn more about these and other changes, you can read the GNOME 50 release notes.

KDE Plasma Desktop

KDE Plasma Desktop: If you are a KDE user, you should also notice a couple of very obvious changes. Fedora KDE Plasma Desktop 44 is based on the latest Plasma 6.6, which includes the new Plasma Login Manager and Plasma Setup to provide a more cohesive and integrated experience from the moment the computer is powered on for the first time. The installation process has been simplified, enabling you to easily set up Fedora KDE Plasma Desktop for a computer for a friend or a loved one.
 

Plumbing Upgrades

Beyond the user-visible changes, there are some important plumbing changes user should be aware of.

OpenSSL Cert File Handling Improvements

The loading time of OpenSSL has been improved by making use of directory-hash support for ca-certificates. This improvement required changes to where some certificate bundles are stored on the filesystem. You can read the specific Change details for more information.

The MariaDB default version is now 11.8

MariaDB packages use a versioned package layout, which allows Fedora to deliver both, mariadb-10.11 and mariadb-11.8 for users.  The “distribution default” unversioned MariaDB packages now install the 11.8 versions in Fedora Linux 44. User doing upgrades to Fedora Linux 44 won’t notice the change in the default. For new users installing MariaDB for the first time, unless you specify the version, you’ll now get 11.8 by default.

Wine NTSYNC

The NTSYNC kernel module is enabled for select packages by package recommendation (notably Wine and Steam), which can improve compatibility and performance when running Windows applications (especially games).  When packages that recommend the wine-ntsync package are installed, the package recommendation ensures NTSYNC is configured automatically on subsequent boots, so that users don’t have to manually enable NTSYNC.

Fedora Cloud boot partition using Btrfs

The /boot partition has been replaced with a Btrfs subvolume for Fedora Cloud images that support it.  This results in better space utilization and smaller images.

If you hit a snag

If you run into a problem, visit our Ask Fedora user support forum. This forum includes a category where we collect common issues and solutions or work-arounds.

Just drop by and say “hello”

Drop by our “virtual watercooler” on Fedora Discussion and join a conversation, share something interesting, and introduce yourself. We’re always glad to see new people!

GDB source-tracking breakpoints

One of the main abilities of a debugger is setting breakpoints.
GDB: The GNU Project Debugger now introduces an experimental feature
called source-tracking breakpoints that tracks the source line a breakpoint
was set to.

Introduction

Imagine you are debugging: you set breakpoints on a bunch of
source lines, inspect some values, and get ideas about how to change your
code. You edit the source and recompile, but keep your GDB session running
and type run to reload the newly compiled executable. Because you changed
the source, the breakpoint line numbers shifted. Right now, you have to
disable the existing breakpoints and set new ones.

GDB source-tracking breakpoints change this situation. When you set a
breakpoint using file:line notation, when this feature is enabled, GDB
captures a small window of the surrounding source code. When you recompile
and reload the executable, GDB adjusts any breakpoints whose lines shifted
due to source changes. This is especially helpful in ad-hoc debug sessions
where you want to keep debugging without manually resetting breakpoints
after each edit-compile cycle.

Setting a source-tracking breakpoint

To enable the source-tracking feature, run:

(gdb) set breakpoint source-tracking enabled on

Set a breakpoint using file:line notation:

(gdb) break myfile.c:42
Breakpoint 1 at 0x401234: file myfile.c, line 42.

GDB now tracks the source around this line. The info breakpoints command
shows whether a breakpoint is tracked:

(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000401234 in calculate at myfile.c:42
source-tracking enabled (tracking 3 lines around line 42)

Now edit the source — say a few lines are added above the breakpoint,
shifting it from line 42 to line 45. After recompiling and reloading the
executable with run, GDB resets the breakpoint to the new line and displays:

Breakpoint 1 adjusted from line 42 to line 45.

Run info breakpoints again to confirm the new location:

(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000401256 in calculate at myfile.c:45
source-tracking enabled (tracking 3 lines around line 45)

As you can see, GDB updated the breakpoint line to match the new location.

Limitations

The matching algorithm requires an exact string match of the captured source
lines. Whitespace-only changes or trivial reformatting of the tracked lines
will confuse the matcher and may cause the breakpoint not to be found.

GDB only searches within a 12-line window around the original location. If
the code shifted by more than that — for example, because a large block was
inserted above — the breakpoint will not be found. GDB will keep the
original location and print a warning:

warning: Breakpoint 1 source code not found after reload, keeping original
location.

Source context cannot be captured when a breakpoint is created pending
(e.g., with set breakpoint pending on), because no symbol table is available
yet. When the breakpoint later resolves to a location, it will not be
source-tracked.

Source tracking is not supported for ranged breakpoints (set with
break-range).

Breakpoints on inline functions that expand to multiple locations are not
source-tracked, as each location may have moved differently.

How to try this experimental feature

This feature is not yet available in a stable GDB release. There are two
ways to try it.

Install from COPR (for Fedora users)

A pre-built package is available through a COPR repository. Enable it and
install:

sudo dnf copr enable ahajkova/GDB-source-tracking-breakpoints
sudo dnf upgrade gdb

To disable the repository again after testing:

sudo dnf copr disable ahajkova/GDB-source-tracking-breakpoints

The COPR project page is at:
https://copr.fedorainfracloud.org/coprs/ahajkova/GDB-source-tracking-breakpo
ints/

Build from source

  1. Clone the GDB repository:
    git clone git://sourceware.org/git/binutils-gdb.git
    cd binutils-gdb
  2. Download and apply the patch from the upstream mailing list:
    https://sourceware.org/pipermail/gdb-patches/2026-April/226349.html
  3. Build GDB:
    mkdir build && cd build
    ../configure --prefix=/usr/local
    make -j$(nproc) all-gdb
  4. Run the newly built GDB:
    ./gdb/gdb

Conclusion

GDB source-tracking breakpoints are an experimental feature currently under
upstream review and not yet available in a stable GDB release. This link
https://sourceware.org/gdb/current/onlinedocs/gdb.html/Set-Breaks.html
covers all available breakpoint commands. If you try this feature out and
hit any kind of unexpected behavior, feedback is very welcome — you can
follow and respond to the upstream patch discussion on the GDB mailing list
at https://sourceware.org/pipermail/gdb-patches/2026-April/226349.html

How to rebase to Fedora Silverblue 44 Beta

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. This article provides the steps to rebase to the newly released Fedora Linux 44 Beta, and how to revert if anything unforeseen happens.

NOTE: Before attempting an upgrade to the Fedora Linux 44 Beta, apply any pending upgrades to your current system.

Updating using the terminal

Because Fedora Linux 44 Beta is not available in GNOME Software, the whole process must be done through a terminal.

First, check if the 44 branch is available, which should be true now:

$ ostree remote refs fedora

You should see the following line in the output:

fedora:fedora/44/x86_64/silverblue

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

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

To remove the pinned deployment use the following command ( “2” corresponds to the entry position in the output from rpm-ostree status ):

$ sudo ostree admin pin --unpin 2

Next, rebase your system to the Fedora 44 branch.

$ rpm-ostree rebase fedora:fedora/44/x86_64/silverblue

The final thing to do is restart your computer and boot to Fedora Silverblue 44 Beta.

How to revert

If anything bad happens — for instance, if you can’t boot to Fedora Silverblue 44 Beta at all — it’s easy to go back. Pick the previous entry in the GRUB boot menu (you need to press ESC during boot sequence to see the GRUB menu in newer versions of Fedora Silverblue), and your system will start in its previous state. To make this change permanent, use the following command:

$ rpm-ostree rollback

That’s it. Now you know how to rebase to Fedora Silverblue 44 Beta and fall 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 Linux? For example from Fedora Silverblue 42 to Fedora Silverblue 44?

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

Question: I have rpm-fusion layered and I got 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 article.

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 Updating using the terminal part of this guide for every ostree edition of Fedora. Just use the corresponding branch. For example for Kinoite use fedora:fedora/44/x86_64/kinoite

As with every beta release, this is your opportunity to contribute by testing out the upcoming Fedora Linux 44 Beta release. Testing the beta release is a vital way you can contribute to the Fedora Project. Your testing is invaluable feedback that helps us refine what the final F44 experience will be for all users.

We hope you enjoy this latest beta version of Fedora!

How to get the Fedora Linux 44 Beta release

You can download Fedora Linux 44 Beta, or our pre-release edition versions, from any of the following places:

The Fedora CoreOS “next” stream moves to the beta release one week later. Content for F44, however, is still available from their current branched stream to enjoy now.

You can also update an existing system to the beta using DNF system-upgrade.

The Fedora Linux 44 Beta release content may also be available for Fedora Spins and Labs.

Fedora Linux 44 Beta highlights

Like every Beta release, the Fedora Linux 44 Beta release is packed with changes. The following are highlights from the full set of changes for F44. They are ready for you to test drive in the Fedora Linux 44 Beta.

Installer and desktop Improvements

Goodbye Anaconda Created Default Network Profiles: This change impacts how Anaconda populates network device profiles. Only those devices configured during installation (by boot options, kickstart or interactively in UI) become part of the final system install. This behavior change addresses some long standing issues caused by populating network profiles for all network devices. These made it difficult to correctly reconfigure devices post-install.

Unified KDE Out of the Box Experience: This change introduces the post-install Plasma Setup application for all Fedora KDE variants. In the variants making use of this new setup application, the Anaconda configuration will be adjusted to disable redundant configuration stages that duplicate the functionality exposed in the setup application.

KDE Plasma Login Manager: This change introduced the Plasma Login Manager (PLM) for Fedora KDE variants instead of SDDM for the default login manager.

Reworked Games Lab: This change modernizes the Games Lab deliverable by leveraging the latest technologies. This offers a high quality gaming and game development experience. It includes a change from Xfce to KDE Plasma to take advantage of the latest and greatest Wayland stack for gaming.

Budgie 10.10: Budgie 10.10 is the latest release of Budgie Desktop. Budgie 10.10 migrates from X11 to Wayland. This ensures a viable long-term user experience for Fedora Budgie users and lays groundwork for the next major Budgie release.

LiveCD Improvements

Automatic DTB selection for aarch64 EFI systems: This change intends to make the aarch64 Fedora Live ISO images work out of the box on Windows on ARM (WoA) laptops. This will automatically select the right DTB at boot.

Modernize Live Media: This change modernizes the live media experience by switching to the “new” live environment setup scripts provided by livesys-scripts and leverage new functionality in dracut to enable support for automatically enabling persistent overlays when flashed to USB sticks.

System Enhancements

GNU Toolchain Update: The updates to the GNU Toolchain ensure Fedora stays current with the latest features, improvements, and bug and security fixes from the upstream gcc, glibc, binutils, and gdb projects. They guarantee a working system compiler, assembler, static and dynamic linker, core language runtimes, and debugger.

Reproducible Package Builds: Over the last few releases, we changed our build infrastructure to make package builds reproducible. This is enough to reach 90%. The remaining issues need to be fixed in individual packages. With this change, all package builds are expected to be reproducible in the F44 final release. Bugs will be filed against packages when an irreproducibility is detected. The goal is to have no fewer than 99% of package builds reproducible.

Packit as a dist-git CI: This change continues down the path of modernizing the Fedora CI experience by moving forward with the final phase of the plan to integrate Packit as the default CI for Fedora dist-git.

Remove Python Mock Usage: python-mock was deprecated with Fedora 34. However, it is still in use in many packages. We plan to go through the remaining usages and clean them up, with the goal of retiring python-mock from Fedora.

Adoption of new R Packaging Guidelines: This change introduces new rpm macros to help standardize and automate common R language packaging tasks resulting in a simplification of the rpm spec files.

Introduction of Nix Developer Tool: This change adds the nix package manager developer tool to Fedora.

Hardlink identical files in packages by default: With this change, all fedora packages will automatically hardlink files under /usr by default as a post install action. The mechanism introduced in this change is designed specifically to address reproducibility validation race conditions found in use by traditional hardlinking approaches.

Fedora Linux 44 Beta upgrades and removals

Golang 1.26: Fedora users will receive the most current and recent Go release. Being close to upstream allows us to avoid security issues and provide more updated features. Consequently, Fedora will provide a reliable development platform for the Go language and projects written in it.

MariaDB 11.8 as Distribution Default Version: The distribution default for MariaDB packaging will switch to 11.8. Multiple versions of the MariaDB packages will continue to be available. This change only impact which of the versioned packages presents itself as the unversioned “default”

IBus 1.5.34: Fedora users will benefit from better support of Wayland and Emoji features.

Django 6.x: Fedora Users can make use of the latest Django version; users who use Django add-ons that are not ready for 6.0 yet should be able to switch it out for python3-django5

TagLib 2: This change puts Fedora on the latest supported version, and it will benefit from improvements in future minor releases with a simple update.

Helm 4: Helm 4 has been released upstream with intentional backwards-incompatible changes relative to Helm 3. To ensure a smooth transition for Fedora, this Change introduces Helm 4 as the default helm package, while providing a parallel-installable helm3 package for users and tooling that still rely on Helm 3.

Ansible 13: Update from Ansible 11 and Ansible Core 2.18 to Ansible 13 and Ansible Core 2.20. This includes major robustness and security fixes to the templating engine which might break existing playbooks that had incorrect behavior. This was silently ignored in previous releases.

TeXLive 2025: With this change, we update to the latest version of TeXLive (2025). We also move to a modularized packaging system, which splits the “texlive” SPEC into a set of collection and scheme packages. This reflects the categorization that TeXLive upstream defines. Each collection package will package the immediate component dependencies as subpackages.

Drop QEMU 32-bit Host Builds: Fedora will stop building QEMU on i686 architecture. This change brings Fedora inline with the QEMU upstream project decision to deprecate support for 32-bit host builds. Upstream intends to start removing 32-bit host build support code in a future release and will assume 64-bit atomic ops in all builds.

Drop FUSE 2 libraries in Atomic Desktops: Remove FUSE 2 binaries and libraries from all Atomic Desktops

Drop compatibility for pkla polkit rules in Atomic Desktops: Remove support for deprecated pkla polkit rules from all Fedora Atomic Desktops
