Comment 3 for bug 1831296

I'd add that it seems to me the "upstream" mode of Ubuntu CI doesn't seem to be actively maintained because unlike the other CI systems used upstream (which are usually fixed almost immediately), it can be broken for weeks (or sometimes even months) which isn't suitable for CI. In principle, if nobody takes care of it, it would probably makes sense to turn off Ubuntu CI upstream (which I did) and switch to the usual release cycle where maintainers try to release the package, catch a lot of bugs (easily preventable by the CI when PRs are opened) and report them upstream. It's far from ideal, of course, but I don't know what else to do about it.
