As of Fedora 18, preupgrade has been replaced by FedUp, which was itself replaced by the DNF_system_upgrade plugin. See Category:Upgrade_system.


This case tests upgrading a Fedora system from the current stable release (Fedora 39) to the branched release (Fedora 40) using PreUpgrade.

How to test

  1. Perform an installation of the stable release (e.g. Fedora 39) with default partitioning (no less than 500MB for /boot).
  2. Do a full system update
  3. Install Package-x-generic-16.pngpreupgrade
  4. Run preupgrade from a command prompt or the Run Application dialog. Provide the requested password for root authorization.
  5. On the Choose desired release screen, enable unstable test releases.
  6. Choose Fedora 40 (Branched) from the list of available upgrade targets, then click Apply.
  7. When the process completes, click Reboot.
  8. The system should reboot, perform the upgrade, and reboot into the new system automatically.
  9. Log in to upgraded system, open a terminal, file browser, or other system applications.

Expected Results

  1. The preupgrade utility will run to completion, without error
  2. The upgrade should complete and reboot without user assistance.
  3. The user is not prompted to address low disk space in /boot
  4. The system should be upgraded to new version without error.
  5. The opened terminal, file browser, or other system applications should display and work correctly.
