10 Essential Steps to Upgrade Fedora Silverblue to Fedora Linux 44

Fedora Silverblue stands as a robust, atomic desktop operating system built on Fedora Linux. It excels for daily use, development, and container-centric workflows, offering rollback capabilities that safeguard your system. If you're ready to rebase to Fedora Linux 44 on your Silverblue installation, this listicle guides you through each critical step. You'll learn not only how to perform the upgrade but also how to revert if any issues arise. Whether you prefer a graphical interface or command-line tools, these 10 steps ensure a smooth transition.

1. Back Up Your Data

Before any major system upgrade, safeguarding your personal files is paramount. While Fedora Silverblue's atomic updates minimize risk, unexpected failures can occur. Use tools like rsync or Deja Dup to back up your home directory and any critical data. If you use encrypted partitions or custom configurations, ensure those are also protected. This precaution gives you peace of mind and a restore point if the rebase process encounters problems. For network shares or cloud storage, verify accessibility post-upgrade. A full backup typically takes 30–60 minutes depending on data size and storage speed.

2. Apply All Pending Updates

Updating your current system to the latest packages before a rebase reduces compatibility issues. Open a terminal and run rpm-ostree update, or use GNOME Software to install all available updates. After updating, reboot to ensure the new deployment is active. This step ensures your base image is as current as possible, minimizing the gap between versions. For atomic desktops like Silverblue, rpm-ostree manages the underlying technology, so the same commands apply to Fedora Kinoite or IoT. Skipping this step might lead to dependency conflicts during the rebase.

3. Check Fedora 44 Availability

Before rebasing, confirm that the Fedora 44 branch is accessible for your architecture. In a terminal, run ostree remote refs fedora. Look for an entry like fedora:fedora/44/x86_64/silverblue. If it's missing, ensure your remote is correctly configured and you have internet connectivity. You can also check the official Fedora mirrors. Availability may vary shortly after release, so patience is key. This verification prevents attempting a rebase to a nonexistent target.

4. Pin Your Current Deployment (Optional)

To preserve your existing system as a fallback option in GRUB, pin the current deployment. Use sudo ostree admin pin 0 where '0' is the index from rpm-ostree status. This keeps that deployment until you manually unpin it. If you later need to revert, you can simply boot into the pinned version. To remove a pinned deployment, run sudo ostree admin pin --unpin 2 (replace '2' with the correct index). Pinning is especially useful if you have custom modifications or experimental software that might not survive a rebase.

5. Rebase via GNOME Software

For a graphical approach, open GNOME Software and navigate to the Updates screen. You'll see a notification about Fedora Linux 44 availability. Click the Download button to fetch the new image. This process may take time depending on your internet speed. Once downloaded, the button changes to Restart & Upgrade. Clicking it triggers the upgrade and automatic reboot. After restart, your system boots into Fedora 44. This method is user-friendly and ideal for those less comfortable with the terminal. The entire process updates the deployment atomically, preserving your home directory and applications.

6. Rebase via Terminal

If you prefer command-line control, rebase from the terminal. First, confirm the target branch is available as in step 3. Then execute rpm-ostree rebase fedora:fedora/44/x86_64/silverblue. This command downloads and stages the new image. After completion, reboot with systemctl reboot. On reboot, GRUB will show the new deployment as the default. The terminal method gives you more transparency into the process and allows scripting for multiple systems. For troubleshooting, review the output for any errors during the rebase.

7. Verify the Upgrade

After rebooting into Fedora 44, verify the upgrade succeeded. Open a terminal and run hostnamectl or cat /etc/fedora-release to confirm the version. Check that your applications and drivers work correctly. For Silverblue, run rpm-ostree status to see the current deployment and rollback options. Testing network connectivity, USB devices, and multimedia playback ensures no drivers are missing. If you encounter issues, you can still roll back using the boot menu. Verification is a quick sanity check before proceeding with daily use.

8. Roll Back if Necessary

If problems arise—like boot failures or software incompatibility—rolling back is straightforward. At boot, press ESC (or hold Shift) to display the GRUB menu. Select the previous version entry. Once booted, make the change permanent with rpm-ostree rollback. This command sets the previous deployment as the default. You can also choose to keep multiple deployments via pinning. Rollback does not affect your home directory or user data. This feature is a major advantage of Silverblue's atomic model.

9. Reinstall Layered Packages

After rebasing, any packages you layered via rpm-ostree install are typically carried over. However, it's wise to check. Run rpm-ostree status and look for layered packages. If some are missing, reinstall them with the same command. Also, rebuild any container images or Flatpak applications to ensure they work with the new kernel and libraries. This step ensures your custom environment is fully functional. For example, if you installed a kernel module, recompile it for the new kernel version.

10. Clean Up Old Deployments

Once you're satisfied with Fedora 44, remove unused deployments to free disk space. Run sudo ostree admin cleanup or use rpm-ostree cleanup -m to remove old base images. Keep only the current deployment and maybe the previous one as a safety net. Regularly cleaning up prevents the boot directory from filling up and reduces clutter in GRUB. This maintenance step is recommended after any major upgrade.

Upgrading Fedora Silverblue to Fedora Linux 44 is a smooth process, whether you choose the graphical or terminal route. By following these 10 steps—from backing up data to cleaning up old deployments—you ensure a reliable transition with minimal risk. The atomic nature of Silverblue makes experimentation safe, and the rollback capability provides a safety net. Now enjoy the enhanced features and performance of Fedora 44 on your atomic desktop.
