Ha! We found the culprit. GID is not supposed to be there, it's not a part. It looks like after an update you started KMail, but did not restart Akonadi, so KMail was sending the "GID" data, but Akonadi did not know it so it though it's a part type.
You can run following query in DB Console to get rid of it: DELETE FROM PartTable WHERE name = 'GID'; This will fix the migration to 1.12 for you. I'll add a check to Akonadi to prevent this from happening to others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1290717 Title: akonadi 1.11.80 fails to start To manage notifications about this bug go to: https://bugs.launchpad.net/akonadi/+bug/1290717/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
