7 Essential Changes in Fedora Atomic Desktops with Fedora Linux 44

Welcome to the latest evolution of Fedora Atomic Desktops! With the release of Fedora Linux 44, the Atomic variants—including Silverblue, Kinoite, Sway Atomic, Budgie Atomic, and COSMIC Atomic—receive a set of impactful updates. These changes aim to streamline development, modernize system libraries, and improve long-term maintainability. Whether you’re a daily driver or an experimenter, understanding these shifts will help you make the most of your Atomic experience. Below, we dive into the seven most significant updates you need to know about.

1. Fedora Linux 44 Arrives for Atomic Variants

Fedora Linux 44 marks another milestone for the Atomic Desktops family. This release brings together all variants under a unified umbrella, ensuring that each desktop environment—from the GNOME-based Silverblue to the cutting-edge COSMIC Atomic—benefits from the same underlying improvements. The core focus remains on providing immutable, container-oriented systems that are both reliable and easy to manage. With better integration across the board, users can expect smoother updates and fewer surprises. If you’ve been waiting to try an Atomic desktop, now is an excellent time to jump in.

2. Issue Tracker Moves to the New Fedora Forge

The cross-variant issue tracker has migrated to the new Fedora Forge platform. This centralized location is now the go-to hub for reporting bugs that affect multiple Atomic Desktops or coordinating work across variant teams. For environment-specific problems (e.g., a bug only in Budgie Atomic), the respective SIG trackers remain the preferred venue. This change simplifies monitoring and triage, making it easier for contributors to collaborate. Check the README of the atomic-desktops organization for links to all relevant trackers. The move aligns with Fedora’s broader shift to a more unified development infrastructure.

3. Unified Documentation Finally Goes Live

One of the most requested features is here: a single, comprehensive documentation site for all Atomic Desktops. Previously, each variant had its own docs, leading to duplication and confusion. Now you can find guides, troubleshooting tips, and configuration references in one place. Note that translations have not yet been migrated—help will be needed once the translation setup is ready on the new forge. Until then, English-language content is fully available. This consolidation reduces maintenance overhead and ensures that updates apply equally to every variant. For more details, track the issue at atomic-desktops#10.

4. FUSE Version 2 Libraries Removed

FUSE 2 has been deprecated upstream for some time, and Fedora 44 removes these libraries from Atomic images. This decision impacts two key areas: AppImages and certain encryption backends. The removal is part of a broader effort to modernize the userland stack. While most applications have moved to FUSE 3 or higher, some older tools still depend on the legacy version. If you rely on such software, you’ll need to adapt. The Fedora Change page and tracking issue atomic-desktops#50 provide further context. Plan ahead to avoid disruptions after upgrading.

5. AppImages: Compatibility Check Required

Some AppImages still bundle an old runtime that requires FUSE 2 libraries. After upgrading to Fedora 44, these AppImages may fail to launch. To check an AppImage’s runtime version, refer to the Discussion thread for examples. If you encounter issues, consider three steps: first, look for a Flatpak version of the same application—Flatpaks are well-integrated with Atomic Desktops. Second, report the problem to the AppImage upstream, encouraging them to adopt a newer runtime. Third, if you can, help upstream package the application as a Flatpak. This approach ensures long-term compatibility and aligns with the Atomic philosophy.

6. Plasma Vault Backends EncFS and CryFS Deprecated

KDE has deprecated the EncFS and CryFS backends for Plasma Vaults, primarily because they rely on FUSE 2. The only remaining supported backend is gocryptfs. If you’re using one of the deprecated backends, migrate your data to a new gocryptfs-based vault before updating to Fedora 44. If you’ve already updated and need access, you can temporarily layer the required packages (cryfs or fuse-encfs) via rpm-ostree install, migrate your data, and then reset the layers with rpm-ostree reset. This process ensures a smooth transition without data loss. For more details, see the tracking issue atomic-desktops#50.

7. Legacy pkla Polkit Rules No Longer Supported

Fedora 44 drops compatibility for the old pkla format of Polkit rules. This change is unlikely to affect most users, as the new JavaScript-based rules have been the standard for years. However, if you have custom pkla files (e.g., from third-party applications or manual configurations), they will no longer be processed. To check, look for files in /etc/polkit-1/rules.d with a .pkla extension. Convert them to the modern .rules format using the polkit tooling or rewrite them manually. This cleanup improves security and consistency across the system.

These seven updates represent the highlights of Fedora Linux 44 for Atomic Desktop users. From documentation consolidation to library modernization, each change aims to make your experience more reliable and future-proof. As always, the Fedora community encourages feedback and contributions. Visit the new issue tracker to report problems, explore the unified docs for guidance, and help with AppImage migration if you can. Embrace the Atomic way—immutable, containerized, and ready for what’s next.
