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.

7. After upgrade finished, reboot the system
8. Login upgraded system and perform some basic desktop operations

   • Open file browser
   • or other system applications

Expected Results

1. The system should be upgraded to Fedora 42 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 opened terminal, file browser, or other system applications should display and work correctly
