From Fedora Project Wiki
- Do a full system update and reboot
- Install the latest version of
fedup
from the stable or updates repository - Find the repository URL for the TC or RC you are testing. This should be of the form https://dl.fedoraproject.org/pub/alt/stage/<milestone>/Fedora/<arch>/os/
- <milestone> is the TC/RC you are testing - e.g. 20-RC1
- <arch> is the name of the arch running on the install to be upgraded (i386, x86_64 ...)
- Start the upgrade prep by executing following command
su -c 'fedup --network <version> --instrepo <URL>'
- <version> is the version of Fedora you are upgrading to (currently 42)
- <URL> is the location found in the previous step
- If you need to use a local mirror to test a brand new change, start the upgrade prep by executing the following command:
su -c 'fedup --network <version> --instrepo <URL> --disablerepo=fedora --repourl fedora-local=<URL-LOCAL>'
- <URL-LOCAL> is the location of a local fedora repo if needed for faster response speeds
- Check
/var/log/fedup.log
file to see if any errors show up in the output fromfedup
- Reboot the system if
fedup
has completed without error - Once the system reboots, there should be a new entry in the GRUB menu titled
System Upgrade
- Select the
System Upgrade
option from the GRUB menu - The system should boot into the upgrade process and a fedup progress screen should be displayed
- Pressing the <ESC> key should switch from the graphical progress screen to the text progress information display
- Once the upgrade process has completed, the system will reboot and an option to boot Fedora 42 will be on the grub menu
- Log in to upgraded system, open a terminal, file browser, or other system applications.
