Fedora 42 has been released! 🎉 So let’s see what is included in this new release for the Fedora Atomic Desktops variants (Silverblue, Kinoite, Sway Atomic, Budgie Atomic and COSMIC Atomic).
Note: You can also read this post on the Fedora Magazine.
New COSMIC Atomic variant
The new COSMIC desktop has been packaged for Fedora and a new Atomic variant created for it thanks to Ryan Brue. It is not yet available on the website but should be soon. See fedora-websites#351. Edit: It is now live: Fedora COSMIC Atomic.
See the Fedora change request.
Changes for all variants
composefs enabled by default
Following Fedora CoreOS in Fedora 41, Fedora Atomic Desktops are now using composefs by default. This is an important first step towards better integrity for the system content.
Note: As a side effect of this change, the systemd-remount-fs.service
unit may fail to start on your system. Until we find a good way to fix this,
you can find a workaround to apply in the
atomic-desktops-sig#72
issue or in the
common issue thread
on the forum.
See the Fedora change request and the tracking issue atomic-desktops-sig#35.
Migration to a static GRUB config
As part of the move to composefs, we had to migrate systems to using a static GRUB config.
This also removes the duplicated entries in the boot menu for installations that pre-dates Fedora 41.
The transition will happen automatically during the first boot on Fedora 42.
You can verify that it worked by looking at the status of the
bootloader-update
service:
$ sudo systemctl status bootloader-update.service
We are still missing documentation on how to change some GRUB settings now that the configuration is static. See the tracking issue atomic-desktops-sig#73.
Custom keyboard layout set on installation (for LUKS unlock)
This fix is important for setups where the root disk is encrypted with LUKS and the user is asked a passphrase on boot. The keyboard layout is now set as a kernel argument during the installation by Anaconda. If you want to later change the keyboard layout used for the LUKS password prompt, you will have to update the kernel argument.
Example to set the keyboard layout to the french keyboard:
$ sudo rpm-ostree kargs --append=vconsole.keymap=fr
Example to replace an existing layout by another:
$ sudo rpm-ostree kargs --replace=vconsole.keymap=de
No longer building for PPC64LE
According to the countme statistics, we did not have users on PPC64LE, so we decided to stop building the Fedora Atomic Desktops for that architecture.
If you relied on those images, you can migrate to Fedora Bootc images (which are available for PPC64LE) or use a conventionnal Fedora package based installation.
See the Fedora change request.
What’s new in Silverblue
GNOME 48
Fedora Silverblue comes with the latest GNOME 48 release.
For more details about the changes that alongside GNOME 48, see What’s new in Fedora Workstation 42 on the Fedora Magazine and Looking ahead at 2025 and Fedora Workstation and jobs on offer! from Christian F.K. Schaller.
What’s new in Kinoite
KDE Plasma 6.3
Fedora Kinoite ships with Plasma 6.3, Frameworks 6.11 and Gear 24.12.
See also What’s New in Fedora KDE Plasma Desktop 42? on the Fedora Magazine.
What’s new in Sway Atomic
Nothing specific this release.
What’s new in Budgie Atomic
The default software center for Budgie Atomic is now Plasma Discover. To rebase from Fedora 41 to 42, you will have to use the command line as rebasing via GNOME Software will move your system to Fedora Silverblue.
See: fedora-budgie/project/issue/5.
Changes in unofficial images
Until we complete the work needed in the Fedora infrastructure to build and push official container images for the Atomic Desktops (see releng#12142 and cloud-image-uploader#37), I am providing unofficial builds of those. They are built on GitLab.com CI runners, use the official Fedora packages and the same sources as the official images.
You can find the configuration and list on gitlab.com/fedora/ostree/ci-test and the container images at quay.io/organization/fedora-ostree-desktops.
Container images signed with cosign (sigstore)
The unofficial container images are now signed with cosign. You can configure your system to verify the signature of the images using the instructions from the project README.
Container images available for aarch64
We are now building all our variants for the aarch64 architecture as well.
Goodbye to Sericea and Onyx (now Sway Atomic & Budgie Atomic)
We have now removed all container images under that name. Use the new names:
- Sericea: sway-atomic
- Onyx: budgie-atomic
Unofficial, experimental Fedora Asahi Remix Atomic Desktops
We are now producing unofficial, experimental bootable container images targeting Apple Silicon, using the packages from the Fedora Asahi Remix project.
Those images are in a working state, but the installation procedure is not ready for general use. We thus only recommend that you give this a try if you are ready to help with the development or are ready to re-install you system and lose data.
See: fedora-asahi-remix-atomic-desktops project on GitHub
See also the Fedora Asahi Remix 42 is now available posts on the Fedora Magazine.
Note that those images currently do not support the x86 emulation detailed in New in Fedora: Running x86 programs on ARM systems.
Universal Blue, Bluefin, Bazzite and Aurora
Our friends in the Universal Blue project (Bazzite, Bluefin, Aurora) have prepared the update to Fedora 42. Look for upcoming announcements in their Discourse.
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 proprietary drivers, extra media codec, out of tree kernel drivers, etc.).
What’s next
Roadmap to Bootable Containers
The next major evolution for the Atomic Desktops will be to transition to Bootable Containers. See also the Fedora bootc documentation.
We have established a roadmap (atomic-desktops-sig#26) and we need your help to make this a smooth transition for all of our existing users.
Turning the sysext experiment into a good experience
Systemd system extensions (sysexts) are a new option when you need some applications available on your system and can not run them in containers or as Flatpaks for various reasons. They offer an alternative approach to package layering as they do not increase update time and can be enabled or disabled as needed.
Support for sysexts is still in development for the Atomic Desktops but they already provide advantages over package layering for some use cases. See the currently experimental project: github.com/travier/fedora-sysexts.
Unifying the Atomic Desktops documentation
We would like to unify the documentation for the Fedora Atomic Desktops into a single one instead of having per desktop environments docs which are mostly duplicate of one another and need to be constantly synced.
See the tracking issue atomic-desktops-sig#10 if you want to help us do that.
Where to reach us
We are looking for contributors to help us make the Fedora Atomic Desktops the best experience for Fedora users.

Historically passwords and credentials in all of our apps and services (such as kio and our Network Manager plasmoid), are stored and managed by our KWallet subsystem and API. In a similar way, GNOME had gnome-keyring, and other similar systems were available. A major problem was the mutually incompatible interface between them, making impossible to have a single place where all the passwords go.
For this reason, a standard DBus interface called Secret Service has been developed, and systems like KWallet, gnome-keyring and KeepassXC have adopted the interface as well.
In the future, we want to eventually port our applications to use the Secret Service API directly, preferably via the QtKeychain library (some applications already do), which will use Secret Service natively on Linux. And as a bonus the Windows/Android native systems on those platforms will work too.
This will make our applications work much better, be more integrated in other desktops or platforms, and be less dependent on the KWallet framework which has big legacy code parts at this point.
Right now, KWallet has the option to bring up a Secret Service compatible interface, and this is a valuable first step, but there are still some potential problems in the migration path:
- Applications using Secret Service will store their secret data in different places when running in different environment, including our own that have been migrated. If you login into a different session ,every app will have forgotten its credentials.
- It’s possible to use a different Secret Service provider also in a Plasma session, for instance enabling it in KeepassXC. At that point some apps will save into it, while other ones will keep using KWallet with a different storage backend.
- Applications ported from KWallet to SecretService will lose their credentials, unless some clunky porting code is written for each application.
A KWallet compatibility layer
Enter the recent refactor that happened in KWallet: it has now been split into 2 different system services now: one that exposes only the Secret Service API, and one that exposes only the KWallet API.
The service exposing the KWallet API has been written from scratch and is now just a thin wrapper around the Secret Service API, translating the KWallet DBus calls to Secret Service ones. The old KWallet service is now a pure Secret Service provider that just happens to use the old KWallet backend, exposing to Secret Service all the entries that had already been stored in the past.
This decouples our KWallet compatibility layer for existing or old applications (not only KDE applications, also third party ones like Chromium use it) with our actual secret storage and SecretService implementation, allowing a separate development roadmap, and even potential future transition to a different backend in a completely transparent way to the user.
You can see this decoupling in the same spirit as the recent KWin Wayland/X11 split: being able to develop the new technology without risking breaking compatibility of the legacy system.
What it means for users and developers
For the immediate future, not much really changes: users will still have all their secrets accessible, and every app they use that was using KWallet will keep working without forgetting anything.
In the same way, for developers, the whole KWallet C++ API keeps working exactly as it was (even though we’re discouraging its use in new projects). Also, the KWallet-to-Secret-Service API proxy layer will save data inside Secret Service with the same schema used by QtKeychain, keeping the data accessible if the application gets ported from using the KWallet C++ API to QtKeychain.
An experimental feature
Disclaimer: The following description is of an experimental feature behind a hidden configuration key: it will take a bit before it’s deemed ready for prime time.
One advantage of having 2 independent services to handle the KWallet API and the Secret Service one is that now it’s possible to chose different backends as well, such as KeepassXC, gnome-keyring or oo7.
Setting the following in kwalletrc:
[Migration]
MigrateTo3rdParty=true
[KSecretD]
Enabled=false
With this, the old KWallet backend (now a service called ksecretd) won’t be started anymore, and instead any Secret Service provider that is running or has been configured to be DBus-activatable will be used. The first time this happens, a data migration procedure will be executed, writing the data in KWallet into the new service, keeping all the user-saved secrets accessible.

Welcome to a new issue of "This Week in KDE Apps"! Every week we cover as much as possible of what's happening in the world of KDE apps.
As Carl is still in vacation, this issue is only partially complete.
System Apps
Dolphin Manage your files
The Dolphin search integration has been rewritten from scratch. Notably, users can now switch the search tool between a simple search algorithm and one using file indexing and offering advanced search options. This way users are no longer forced to use the file index whenever it is available and can instead search in a slower but more reliable manner.
The overall user interface design is much improved with better clarity about what is currently being searched and which parameters can be changed. It was designed in a collaborative effort by Kristen McWilliam, Jin Liu, Andy Betts, Tagwerk, Felix Ernst, and a few others. (Felix Ernst, 25.08.0. Link)
The "Show in Groups" action was moved from the "View" menu to the "Sort By" menu. (Nate Graham, 25.08.0. Link)
The "Change View Mode" button which was recently added to Dolphin's default tool bar configuration is now icon-only by default (just like we had intended). (Akseli Lahtinen, 25.08.0. Link)
In the Trash context menu the "Properties" action is now once again in the last position just like in all the other Dolphin view context menus. This now-fixed inconsistency was an unintended side-effect of us moving the "Delete" action last to make it less likely to click it by accident when aiming at "Restore". (Kai Uwe Broulik, 25.08.0. Link)
Dolphin will now hide the background of the navigation bar when it's outside of the toolbar. (Akseli Lahtinen, 25.08.0. Link)
Other
Various improvements were made for the KDE Open and Save dialog:
- People using single-click selection can now click on checkboxes to select individual items in multi-selection dialogs. This works similarly to how it does in Dolphin. (Akseli Lahtinen, KIO 6.14. Link)
- Open and Save dialogs now allow quickly filtering through files by filename when pressing CTRL+I or Backslash key, like in Dolphin. (Akseli Lahtinen, KIO 6.14. Link)
…And Everything Else

Finishing Up
Hey everyone, It’s me again, back with the final update for this year’s Season of KDE. So, turns out things don’t really go as planned and it took me some extra time to bring it over the line.
Since my last post, I wrote the tests for the Kalah game, the associated TUI, a greedy move selection and benchmarked Oware and Bohnenspiel. My mid-sem exams happened, in between, and delayed me by 2 weeks.
Dear fans of music & open source music players,
in preparation of the upcoming Amarok 3.3 release, a beta release (3.2.81) has been prepared.
As shown in the ChangeLog, the changes are mostly technical: Qt5 support is removed, and Amarok 3.3 beta is compatible with Qt6/KF6 only. Additionally, a database scheme update (first such since 2012) fixes encoding and date related bugs.
Please note that due to the database update, downgrading from 3.3 beta is not directly possible, and returning to pre-3.3 versions requires the database (at ~/.local/share/amarok/mysqle/) to be manually backed up beforehand.
Aligning with current major KDE Frameworks version should simplify various direct and indirect software dependencies. However, phonon-vlc is the only supported backend on Qt6 Phonon, which Amarok 3.3 beta is still using for audio playback. This imposes some constraints e.g. on equalizer and analyzer functionalities. A more comprehensive overview of audio backend status is available on an invent.kde.org issue and a related work-in-progress merge request.
Additionally, there isn't official releases with Qt6 support of liblastfm available yet (needed for last.fm support). To enable the functionality, one needs to use library version built from e.g. sources at https://github.com/Mazhoon/liblastfm/tree/81e8f9dc16a0a18fe9a066d51c2071086326670b .
The Amarok 3.3 beta source tarball is available on download.kde.org and it has been signed with Tuomas Nurmi's GPG key. In addition to the source code, it is likely that some distributions will provide beta packages. The various nightly git builds provided by various splendid packagers should also provide a way of using the beta changes and participating in the testing.
Happy listening!
Final update
So this is my final blog regarding the Season of KDE 2025, I’m feeling happy for what I accomplished. Over the past few weeks, I’ve implemented PvP system for mancala game, this project has been a deep dive into game development, networking and user experience.
Summary of work done so far
1. Move tracking Mechanics
At the heart of this project lies the MankalaEngine
, an engine designed to handle rules and gameplay of various mancala variants. I’ve added some more feature in the engine:
- Move tracking: The
lastMoveMethod()
method allows to retrieve the last move played by the player and computer.
2. PvP Mode
It allows the real-time multiplayer gameplay using XMPP. Following is a brief summary:
- XMPP Integration: Players connect to each other using their jabber IDs and exchange move using the established chat room in real-time.
- Turn Management: The Player 1 always start, and turns alternate between the two players.
- Board Syncing: Players manually update their boards based on the opponent’s move, ensuring both the players have accurate view of the game state.
3. Man Page Documentation
To make the game accesible, I’ve created a man page for bohnenspieltui
. This man page provides the information abou the game, including:
- Synopsis and Description: A brief overview and explanation of the game variant.
- Usage: Instructions for running the PvP mode.
- Added a minor improvement of card view in Mancala GUI.
Future Work
While the task for this term is completed, their are several areas for improvement:
- Automated board syncing by replacing the current manual one.
- Integrating the engine to the mancala GUI.
- Extending the PvP to other variants.
Final Words
Thanks to KDE community, XMPP community and Benson Muite and João Gouveia and Blue from Macaw.me for the guidance and support. And I encourage the aspiring contributors to take part in Season of KDE to learn and grow as a developer.

It looks like Brodie Robertson hasn’t gotten sick of me yet, because we sat down again recently, this time on the subject of Techpaladin! We go over a lot of stuff I wrote in the announcement blog post last month, plus more detail and other topics too. This ends up being a pretty nerdy talk as we additionally meander between finance and exchange rates, Dungeons and Dragons, Alpha Centauri, Maslow’s Hierarchy of needs, the KWin Zoom effect, and, of course, KDE World Domination.
Welcome to a new issue of "This Week in Plasma"! Every week we cover the highlights of what's happening in the world of KDE Plasma and its associated apps like Discover, System Monitor, and more.
This week there's big news: at long last, KWin has gained support for the initial version of the Wayland session restore protocol! This work was done by David Edmundson and Vlad Zahorodnii, and lands in Plasma 6.4.
Now, before you go celebrate in the streets, there are some big caveats:
- This version of the protocol only supports window sizing, positioning, and virtual desktop placement.
- It doesn't govern windows saving their internal content yet. That's coming later.
- Toolkits and apps still need to opt in; nothing automatically starts working for free.
But this point is… this stuff is coming soon and in motion! Exciting times.
