Description

This case tests upgrading a Fedora system from the current stable release (Fedora 41) to the development release (Rawhide/Fedora 42) using PreUpgrade.


How to test

  1. Perform an installation of the stable release (e.g. Fedora 41) with default partitioning (200MB for /boot).
  2. Find out how much space is available on the /boot filesystem. df is the command you want for this:
$ df /boot
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1               198337     30543    157554  17% /boot
  1. Create a file that takes up enough space that preupgrade decides it cannot install stage2 now. Preupgrade needs approximately 120MB for the installer image so we'll make sure we have a bit less than 100MB. For the example filesystem, that means we need to fill up 60MB. Here's how to do that as root:
# dd if=/dev/zero of=/boot/preupgrade_filler bs=1024 count=61440
# df /boot
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1               198337     92224     95873  50% /boot
  1. Install the newest available version of preupgrade.
  2. Run preupgrade from a command prompt or the Run Application dialog. Provide the requested password for root authorization.
  3. On the "Choose desired release" screen, enable "unstable test releases".
  4. Choose Rawhide from the list of available upgrade targets, then click Apply.
  5. Preupgrade will present a warning dialog noting that additional disk space in /boot is required to complete the upgrade process. Remove older kernels by consulting the instructions at How_to_use_PreUpgrade#Troubleshooting to free more space in /boot], then click Check again
  6. When the process completes, click Reboot.
  7. The system should reboot, perform the upgrade, and reboot into the new system automatically.
  8. 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 users are prompted with a low disk-space warning.
  3. Removing older kernels allows the upgrade to proceed beyond the low disk-space warning.
  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.
