So, if do-release-upgrade -d is used, upstart is in fact upgraded before mysql, and this problem does not appear. I'm lowering this to Medium, since that is by far the preffered method.
Unfortunately a much more serious issue turned up, where /run/mysql/mysqld.sock is not writable due to the apparmor profile. ** Changed in: mysql-5.5 (Ubuntu) Importance: High => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907465 Title: mysql upstart job must depend on upstart >= 0.6.7-2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debhelper/+bug/907465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
