I suspect something is broken with dbus as the 'service' command doesn't work either. For example:
$ service network-manager restart Failed to retrieve unit: Failed to active service 'org.freedesktop.systemd1': timed out Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24) Could not watch jobs: Connection timed out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757458 Title: Kubuntu installer crash [HP ProBook 640 G1] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1757458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
