[Bug 2047447] Re: No valid source.list found while upgrading from mantic to noble

[Julian Andres Klode]

The comment one is fixed in noble, I'm not sure what Xavier's
ubuntu.sources is about though, there's probably subtle errors in there
that get lost in the comment. So...

Suffice it to say, this is a rather niche issue as 23.10 did not
actually ship with ubuntu.sources, so it affects a few people who
upgraded to it during the development cycle while that was on. I could
look at backporting the fix in python-apt and I guess more importantly,
the case-insensitive lookup. I don't think backporting this on its own
makes a lot of sense given that this only affects early 23.10 testers,
but the case-sensitiveness fix probably makes it worth it.
