I worked around it by running: sudo apt-get purge systemd-sysv

The problem is that ubuntu- minimal gets installed on upgrades, and that it depends on upstart and ureadahead which clash with systemd-sysv. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1405943 Title: update-manager -d failing from 14.10 to 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1405943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
