Fedora 24 just became available and is officially released. You’ll likely want to upgrade your system. If you’ve upgraded from past Fedora releases, you may be familiar with the
upgrade plugin. This method is the recommended and supported way to upgrade from Fedora 23 to Fedora 24. Using this plugin will make your upgrade to Fedora 24 simple and easy. Note also that shortly after the release of Fedora 24, you will also be able to update to Fedora 24 Workstation using the Software app.
1. Update software and back up your system
Before you do anything, you will want to make sure you have the latest software for Fedora 23 before beginning the upgrade process. Additionally, make sure you back up your system before proceeding. One popular tool available in Fedora for this purpose is deja-dup. To update your software, use GNOME Software or enter the following command in a terminal.
$ sudo dnf upgrade --refresh
2. Install the DNF plugin
Next, open a terminal and type the following command to install the plugin:
$ sudo dnf install dnf-plugin-system-upgrade
3. Start the update with DNF
Now that your system is up-to-date, backed up, and you have the DNF plugin installed, you can begin the upgrade by using the following command in a terminal:
$ sudo dnf system-upgrade download --releasever=24
This command will begin downloading all of the upgrades for your machine locally to prepare for the upgrade. If you have issues when upgrading because of packages without updates, broken dependencies, or retired packages, add the
flag when typing the above command. This will allow DNF to remove packages that may be blocking your system upgrade.
4. Reboot and upgrade
Once the previous command finishes downloading all of the upgrades, your system will be ready for rebooting. To boot your system into the upgrade process, type the following command in a terminal:
$ sudo dnf system-upgrade reboot
Your system will restart after this. In past releases, the
tool would create a new option on the kernel selection / boot screen. With the new
package, your system reboots into the current kernel installed for Fedora 23; this is normal. Shortly after the kernel selection screen, your system begins the upgrade process.
Now might be a good time for a coffee break! Once it finishes, your system will restart and you’ll be able to log in to your newly upgraded Fedora 24 Workstation.
Resolving upgrade problems
On occasion, there may be unexpected issues when you upgrade your system. If you experience any issues, please visit the DNF system upgrade wiki page for more information on troubleshooting in the event of a problem.
If you are having issues upgrading and have third-party repositories installed on your system, you may need to disable these repositories while you are upgrading. For support with repositories not provided by Fedora, please contact the providers of the repositories. Many users of third-party repositories also have had issues with packages not being properly signed. For help resolving that issue, you can read this blog post from Kamil Páral.
