Comment 4 for bug 875657

Ah, okay. If it's a remote session thing, then that's definitely different. I've just done some quick research and it seems that the policykit authorization policy that the QApt worker uses by default disallows remote access, such as via an nx server. When I get home tonight I can post a replacement policy file to be placed at /usr/share/polkit-1/actions/org.kubuntu.qaptworker.policy
