Upgrade & Releases

Fedora Release Cycle Explained: How Often Does Fedora Release New Versions? Fedora releases new versions every 6 months with rawhide as the continuous development branch. Fedora Version End of Life (EOL): When to Upgrade and What Happens If You Don't Fedora reaches EOL every 6 months, stopping security updates; upgrade immediately using dnf system-upgrade to maintain security and functionality. Fix issues after upgrade Most post-upgrade problems on Fedora — broken packages, service failures, SELinux denials, or bootloader issues — are resolved by running a full system sync, relabeling SELinux contexts, and rebooting into the new kernel. How to Check Your Current Fedora Version You can quickly identify your current Fedora version by running `cat /etc/fedora-release` or by checking the `NAME` and `VERSION_ID` fields in `/etc/os-release`. How to Check Your Current Kernel Version on Fedora Run `uname -r` in your terminal to instantly display the currently running kernel version, or check `/proc/version` for a more detailed build string. How to Downgrade Fedora to a Previous Version (And Why It's Risky) Fedora does not support full OS version downgrades, but you can roll back individual packages with dnf, or restore a previous OS snapshot if you planned ahead with Btrfs or a VM. How to Fix a Failed Fedora System Upgrade Fix a failed Fedora upgrade by downloading the new release version and rebooting the system. How to Fix Broken Packages After a Fedora Version Upgrade Resolve broken or mismatched packages after a Fedora release upgrade by running `dnf distro-sync`, reinstalling conflicting packages, and cleaning up retired or orphaned software. How to Fix Missing or Broken Desktop After Fedora Upgrade Fix a missing or broken Fedora desktop after an upgrade by reinstalling the desktop environment packages and restarting the display manager. How to Install a Specific Kernel Version on Fedora Install a specific kernel version on Fedora using dnf and update the bootloader configuration. How to Install Java (OpenJDK) on Fedora and Manage Multiple Versions Install OpenJDK on Fedora using dnf and switch between versions with the alternatives command. How to Migrate Virtual Machines on Fedora Migrate KVM virtual machines between Fedora hosts using virsh live migration over SSH or by exporting and transferring disk images for offline moves. How to Prepare Your System Before Upgrading Fedora A few minutes of preparation before a Fedora version upgrade — backing up data, applying pending updates, and checking disk space — dramatically reduces the chance of a failed or broken upgrade. How to Roll Back a Fedora System Upgrade Roll back a failed Fedora upgrade by booting the previous kernel from GRUB, restoring a Btrfs snapshot, or downgrading packages with DNF. How to Skip a Fedora Version During Upgrade (e.g., 40 to 42) Fedora requires sequential upgrades through each intermediate version; you cannot skip from 40 to 42 directly. How to Upgrade Fedora 39 to Fedora 40 Upgrade Fedora 39 to Fedora 40 using the dnf system-upgrade command to download and reboot into the new release. How to Upgrade Fedora 40 to Fedora 41 Upgrade Fedora 40 to Fedora 41 using the dnf system-upgrade command to download new packages and reboot. How to Upgrade Fedora 41 to Fedora 42 Upgrade Fedora 41 to Fedora 42 using dnf system-upgrade with the releasever flag. How to Upgrade Fedora Kernel Without Full System Upgrade You cannot upgrade the Fedora kernel independently; run a full system update with dnf to safely install the latest kernel. How to Upgrade Fedora to the Latest Version (System Upgrade Guide) You can upgrade Fedora to the latest version in-place using the `dnf system-upgrade` command, which downloads all necessary packages and reboots the system to complete the transition. Pre-upgrade checklist Before upgrading Fedora to the next release, back up your data, verify disk space, check third-party repositories, and confirm the system is fully up to date. Upgrade to Latest Fedora Version Use the `dnf system-upgrade` plugin to safely upgrade your Fedora installation to the latest release in a few commands.
