Could you try sudo stop cgmanager || true sudo /sbin/cgmanager -m name=systemd
and paste the output here? Maybe for good measure also do sudo strace -f -ooutput /sbin/cgmanager -m name=systemd and attach the file called 'output' Thanks! It's possible this happened due to the switch to and from systemd, but it still would be great to know what exactly happened and whether it'll affect others. status: incomplete importance: high ** Changed in: cgmanager (Ubuntu) Importance: Undecided => High ** Changed in: cgmanager (Ubuntu) Status: Invalid => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1407954 Title: package cgmanager 0.32-4ubuntu1.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgmanager/+bug/1407954/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
