So far, it's all about the introduction of too-many-positional-arguments, we can leave that alone.

Fix issues like this one, which have just started happening: https://github.com/mulkieran/justbases/actions/runs/12173300600/job/33953420489 . Likely this is due to a change in the GitHub test environment, since it didn't happen to justbytes a few days ago and justbytes is set up identically. The failure is to be unable to import setuptools, even though it has been installed. I think the solution is to find a way to install setuptools later in the test steps, so it ends up within the virtual environment that GitHub uses.

I think all remaining PRs just need a rebase or possibly to disable a lint, except for the PR stratis-storage/into-dbus-python#117, with the late-appearing astroid bug.
