lp-propose fails if the target branch has an inaccessible parent branch

[Didier Roche-Tolomelli]

when trying: bzr lp-propose lp:bamf -m "foo":
bzr: ERROR: bzrlib.errors.InaccessibleParent: Parent not accessible given base "bzr+ssh://bazaar.launchpad.net/+branch/bamf/" and relative path "../../../~anjali-team/anjali/bamf/"

This is because the anjali-team bamf branch is not used anymore and removed (the current lp:bamf is under ~unity-team and the one used for now).

When looking at potential parent branch, we should be catching it and just skipping that one.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

Wow, 2+ years and this is still happening.

bzr: ERROR: Parent not accessible given base "bzr+ssh://bazaar.launchpad.net/+branch/cupstream2distro/" and relative path "../../../+branch/cupstream2distro/"

What's the workaround? Change the team ownership of the branch?
