Please make sure all the broken GHA tests are unrelated!

[jmtd]

Please make sure all the broken GHA tests are unrelated!

Confirmed: they are all failing in the configure step due to some kind of Ubuntu repository signing problem. I don't know if that is transient or if we have a tracker for it yet

E: Failed to fetch https://packages.microsoft.com/ubuntu/22.04/prod/dists/jammy/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: The repository 'https://packages.microsoft.com/ubuntu/22.04/prod jammy InRelease' is no longer signed.
