Let me know if you prefer different commits/PRs for each of the changes.
Note that GHA is failing with the following message:

E: Unable to locate package python3.9
E: Couldn't find any package by glob 'python3.9'
E: Couldn't find any package by regex 'python3.9'

Can't really tell why this is happening (it's on ubi8 after all).
