[Jelmer Vernooij (jelmer)]

This looks like a Launchpad error, though we should probably handle it and not print a traceback.

[Paride Legovini (paride)]

I believe this due to the fact that breezy 3.3.0 (or 3.3.1) handles the lp: shorthand differently from what it used to do. For example

  bzr branch lp:libappindicator

works fine on Jammy, but fails as described on Lunar.

[Jelmer Vernooij (jelmer)]

Yes, things have changed - breezy has switched to using the main Launchpad API rather than the older XML/RPC API.

That said, Launchpad shouldn't be serving a 500 in this case.

[Jelmer Vernooij (jelmer)]

Fix in the attached branch. Filed bug #2002568 in Launchpad about the 500.

[Paride Legovini (paride)]

I tested it and it appears to be working fine. Thanks for fixing this so quickly!

What's your plan for releasing 3.3.2? I'm asking as this bug is currently preventing some Ubuntu automated testing from working correctly, and we may want to have the fix land to Lunar sooner than later.

[Able Chow (ablechow)]

Thank you for addressing this issue.
Happy new year and have a wonderful week!

I can probably release 3.3.2 this weekend. If that's too late, you're probably better off cherry-picking it in Ubuntu.

[Paride Legovini (paride)]

Thanks. It is not _that_ urgent but given that this should be a straightforward cherry-pick I may upload it to Lunar tomorrow and then make sure it syncs once you upload 3.3.2 to Debian.
