From Fedora Project Wiki

As of Fedora 18, installer-based upgrades have been replaced by FedUp, which was itself replaced by the DNF_system_upgrade plugin. See Category:Upgrade_system.


This case tests upgrading from the current stable release (Fedora 40) to the development release (Fedora 41) while updating the existing bootloader configuration in text mode.

How to test

  1. Perform a default installation of the previous Fedora release (Fedora 40)
  2. Do a full system update
  3. Modify the bootloader configuration (e.g. grub.conf, yaboot.conf, elilo.conf or zipl.conf depending on your platform). Append several useless kernel arguments and increase the boot timeout. You're looking to make enough changes that you can verify they remain after the upgrade. For example, considering adding a kernel boot arguments: TESTING=cool ABC.
  4. Boot the Fedora 41 installer using any available means (boot.iso, PXE or DVD.iso) , passing the command line argument text
  5. After anaconda is started successfully, select default language,keyoard, and then select the system to be upgraded
  6. Select Update boot loader configuration to upgrade
  7. After upgrade finished, reboot the system
  8. Login upgraded system and perform some basic operations

Expected Results

  1. The system should be upgraded to Fedora 41 version without error
  2. The bootloader configuration changes are present in the upgraded system
  3. The system can boot into new version fedora without error
  4. The system applications should work correctly
