The actual error is in the upstream module itself - where they missed to specify configobj as a build dependency in setup.py file that is used to build wheels.
They correctly specified it in the - https://github.com/breezy-team/breezy/blob/3.2.0-1/debian/control debian control file but missed in the setup.py file for some reasons. We should either add a comment to indicate why are we introducing a non-setup deps in setup.txt and remove it later when we upgrade breezy. -- https://code.launchpad.net/~lgp171188/launchpad/+git/launchpad/+merge/478587 Your team Launchpad code reviewers is requested to review the proposed merge of ~lgp171188/launchpad:fix-breezy-wheel-build-make-configobj-a-setup-requirement into launchpad:master. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-reviewers Post to : launchpad-reviewers@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-reviewers More help : https://help.launchpad.net/ListHelp
