I forward the information from this bug report here: https://bugs.launchpad.net/ubuntu/+source/cups-pk-helper/+bug/934291 Deleting or stopping print jobs through the "gnome-control-center -> printers" menu is not possible. (Black rectangle for stopping can be pressed, nothing happens.) Deleting with cups via webinterface does work. ( http://localhost:631/ ) [Impact] The most intuitive way for users to maintain printers and look after print jobs is the printing part of the GNOME Control Center. As this tool makes use of cups-pk-helper for authentication, a lot of its functionality is not working dur to the non-working in cups-pk-helper package. This way a key functionality in Ubuntu Desktop is not working which may people turn away from Linux on the desktop. [Test Case] Do job operations (remove, move to other printer, ...) with print jobs using the printing tool of GNOME Control Center ("Devices" -> "Printers"). You will see that most or all of these operations do not work.
