This is a bug in the uck script, not in upstart. It deactivates initctl by doing the following:
echo "Deactivating initctl..." chroot "$REMASTER_DIR" mv /sbin/initctl /sbin/initctl.uck_blocked chroot "$REMASTER_DIR" ln -s /bin/true /sbin/initctl By not using dpkg-divert on initctl, when a new version of upstart is itself unpacked as part of the upgrade, /sbin/initctl is overwritten. ** Package changed: upstart (Ubuntu) => uck (Ubuntu) ** Changed in: uck (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/886843 Title: upstart 1.3-0ubuntu11 causes cups install fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/uck/+bug/886843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
