Comment 15 for bug 1090656

Sebastian, are we sure this is really about policykit and aptdaemon? The issues don't seem very well described to me and I recently discovered an issue with libgksu2-0 having its authentication mode set to su instead of sudo. This would affect gdebi which is also used to install and remove packages. Anyway, that's bug 1173013.

Anybody experiencing this bug may want to try the command 'gksu-properties', in a terminal, and see what the authentication mode is set to. If it is 'su' change it to 'sudo'. If you don't have gksu-properties installed then this isn't bug 1173013.
