Hm, that didn't work , probably because you didn't provide a PID. I was silly, since you're on Lubuntu, gnome-settings-daemon isn't running. So start users-admin, get its PID using 'pidof users-admin', and replce $PID with this value in the command.
BTW, you can paste command outputs directly here. In this case they were too long because there was an error, so you could just have told that the manual page was shown. For long outputs, attaching a log file is best. -- Polkit authentication fails in Lubuntu https://bugs.launchpad.net/bugs/599050 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-system-tools in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
