Also, if(!) this is due to EOL (this week doesn't match the EOL dates, though), why does 23.04 still work?

Idk! But the GitHub Actions have been failing since last week, not just today. #10248.

There is no functional dependency on this so I don't see why this should stop this PR. Currently, this leads to failing GitHub Actions for all newly created PRs.

Dunno. Delays? Someone forgot it 6 months ago?

Anyway, now both seem to be gone:

Dunno, but 23.04 is now also failing, https://github.com/Icinga/icinga2/actions/runs/12028013126/job/33530223413. I guess the Ubuntu repository maintainers have realized they have forgotten to sunset 23.04 after removing the 23.10 repo.

It's dead, Jim.
