I think this is because the user was not a member of the group "admin", I don't know if this is changed behaviour since 10.10, because I only notice this now. Previously the user was a member of adm, but not admin.
In user management, selecting "user may administer the system" invokes this change. IMO, If this was a change from 10.10 to 11.04, it's a bug in the upgrade process, otherwise I don't think this is a software bug, but more likely a documentation bug in some way? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/758592 Title: KPackageKit fails to obtain authentication -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
