| {{QA/Test_Case
| |
| |description=This case tests upgrading a Fedora system from the current stable release ({{FedoraVersion|long}}) to the development release (Rawhide/{{FedoraVersion|long|next}}) using [[PreUpgrade]].
| |
| {{admon/note|Note|This test requires you to have a wired connection to the internet during the install.}}
| |
| |actions=
| |
| # Perform an installation of the stable release (e.g. {{FedoraVersion|long}}) with default partitioning (200MB for <code>/boot</code>).
| |
| # Find out how much space is available on the {{filename|/boot}} filesystem. {{command|df}} is the command you want for this:
| |
| <pre>
| |
| $ df /boot
| |
| Filesystem 1K-blocks Used Available Use% Mounted on
| |
| /dev/sda1 198337 30543 157554 17% /boot
| |
| </pre>
| |
|
| |
|
| # 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:
| |
| <pre>
| |
| # 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
| |
| </pre>https://fedoraproject.org/wiki/How_to_use_PreUpgrade#Troubleshooting
| |
| # Install the newest available version of {{package|preupgrade}}.
| |
| # Run <code>preupgrade</code> from a command prompt or the ''Run Application'' dialog. Provide the requested password for root authorization.
| |
| # On the "Choose desired release" screen, enable "unstable test releases".
| |
| # Choose ''Rawhide'' from the list of available upgrade targets, then click ''Apply''.
| |
| # Preupgrade will present a warning dialog noting that additional disk space in {{filename|/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''
| |
| # When preupgrade is done don't reboot immediately. Instead, remove the /boot/preupgrade_filler file and make sure your computer is connected to the network via an ethernet cable. Then you can reboot.
| |
| <pre>
| |
| # rm /boot/preupgrade_filler
| |
| </pre>
| |
| # The computer should boot into the installer, connect to the internet via the ethernet cable and start downloading the stage2 installer image. Then it should continue upgrading as normal.
| |
| |results=
| |
| # The preupgrade utility will run to completion, without error.
| |
| # The users are prompted with a ''low disk-space'' warning.
| |
| # Removing older kernels allows the upgrade to proceed beyond the ''low disk-space'' warning.
| |
| # The system should be upgraded to new version without error.
| |
| # The opened terminal, file browser, or other system applications should display and work correctly.
