Template:Dnf upgrade procedure

1. Do a full system update and reboot
2. Install the latest version of dnf-plugin-system-upgrade from the stable or updates repository
3. Start the upgrade prep by executing:
   • sudo dnf system-upgrade download --releasever=40
   • You can change the releasever to test upgrading to a different release, of course
4. If you need to use a local mirror to test a brand new change, you can enable it as normal, e.g.:
   • sudo dnf system-upgrade download --releasever=40 --enablerepo=<name>
5. To aid debugging, run this command to enable a root shell on VT9 during the upgrade boot:
   • sudo systemctl add-wants system-update.target debug-shell.service
6. If dnf system-upgrade download has completed without error, run:
   • sudo dnf system-upgrade reboot
7. Once the system reboots, the system should boot into the upgrade process and a graphical progress screen should be displayed
   • Pressing Esc should switch from the graphical progress screen to the text progress information display
8. Once the upgrade process has completed, the system should reboot and an option to boot the new release should be on the grub menu
9. Log in to the upgraded system, open a terminal, file browser, or other system applications
