QA:Testcase Preupgrade from older release

Description

This case tests upgrading a Fedora system from the previous stable release (Fedora 40) to the development release (Rawhide/Fedora 42) using PreUpgrade.

How to test

1. Perform an installation of the previous stable release (e.g. Fedora 40) with default partitioning (no less than 200MB for /boot).
2. To model a real-world use case, ensure there are a total of three kernels installed on the system. You can locate and download older kernels from the koji build system or by using a koji. For example, the following commands will list available kernels and download a specified kernel package from koji.

   # yum install koji

   # koji list-tagged --quiet dist-f11-updates kernel

   # koji download-build --arch $(uname -p) --arch noarch kernel-2.6.30.5-43.fc11

3. Install the newest available version of preupgrade.
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 Rawhide from the list of available upgrade targets.
7. Click Apply.
8. NOTE - Preupgrade may present a warning dialog noting that additional disk space in /boot is required to complete the upgrade process. See methods to free more space in /boot, then click Check again
9. When the process completes, click Reboot.
10. The system should reboot, perform the upgrade, and reboot into the new system automatically.
11. 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 system should be upgraded to new version without error.
4. The opened terminal, file browser, or other system applications should display and work correctly.
