Title:

Looking closer at the code, this is already supposed to be handled, but
there is a control flow mistake. The logs hint at this too:
2024-10-02 17:30:48,273 ERROR No 'ubuntu-minimal' available/downloadable after
sources.list rewrite+update
2024-10-02 17:30:48,273 ERROR 'ubuntu-minimal' was not in
Our options here are:
* Do not continue if ubuntu-minimal is not installed.
* Install ubuntu-minimal first before trying to upgrade
* Catch the KeyError
* Add a global catch-all that always tries to rollback.

This is a funny instance where ubuntu-minimal isn't even installed, so
after upgrading the sources we don't see one, so we fail a step too
early with a crash instead of doing a clean rollback.
