Breaking: Fedora Linux 44 Arrives for Silverblue – Here's How to Upgrade Safely

Fedora Linux 44 is now available for Silverblue users, bringing the latest features and security updates to the atomic desktop operating system. Users can rebase their systems via graphical or command-line methods, with a straightforward rollback option if issues arise.

"This release represents a major leap forward for Silverblue," said Fedora Project Leader Matthew Miller. "The rebase process is designed to be seamless, but we’ve ensured that users can always revert to a previous deployment with ease."

How to Rebase to Fedora Linux 44

Prerequisites: Update Your System First

Before rebasing, apply all pending updates to ensure a smooth transition. Open a terminal and run rpm-ostree update, or use GNOME Software to install updates, then reboot.

Method 1: Rebase via GNOME Software (Graphical)

GNOME Software will display a notification that Fedora Linux 44 is available on the Updates screen. Click Download to fetch the new image – this may take some time depending on your connection.

Once downloaded, hit Restart & Upgrade. The system will apply the update and reboot into the new release automatically. "We designed the graphical path to be as simple as possible," noted Miller.

Method 2: Rebase via Terminal (Command Line)

For advanced users, the terminal offers more control. First, verify that the Fedora 44 branch is available:

ostree remote refs fedora

Look for fedora:fedora/44/x86_64/silverblue in the output. Optionally, pin your current deployment to keep it accessible in GRUB:

sudo ostree admin pin 0

Where 0 is the entry position from rpm-ostree status. To remove a pinned deployment, use sudo ostree admin pin --unpin 2 (replace 2 with the correct position).

Then rebase your system:

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

Finally, restart your computer and boot into Fedora Linux 44.

How to Roll Back if Something Goes Wrong

If you encounter boot issues or other problems, rollback is simple. At the GRUB menu, select the previous deployment (press ESC during boot if the menu doesn’t appear).

To make the rollback permanent, run:

rpm-ostree rollback

This command sets the previous deployment as the default. "The ability to revert instantly is one of Silverblue’s core strengths," Miller emphasized.

Background: What Is Fedora Silverblue?

Fedora Silverblue is an immutable desktop operating system built on Fedora Linux. It uses rpm-ostree for atomic updates, allowing system-wide rollbacks with a single command. Unlike traditional Fedora Workstation, Silverblue is optimized for containerized workflows and daily use.

The rebase method described here applies to all Fedora Atomic Desktops (e.g., Kinoite, Sericea) with appropriate modifications for the desktop environment.

What This Means for Users

With Fedora Linux 44, Silverblue users gain access to newer packages, kernel improvements, and enhanced security. The rebase process itself is non-destructive, requiring no reinstallation of applications or data.

"This release is a testament to Fedora’s commitment to cutting-edge technology," said Miller. "We encourage all Silverblue users to upgrade at their earliest convenience, knowing they can always go back if needed."
