Correct, the problem occurred before ever opening users-admin. I agree with moving the bug after the remaining rights issue is resolved.
Terminal log below. The account having the problem is "tristan". The account that didn't experience problems is "kateryna". Note though that the kateryna account does not have the administer permission nor the "configure printers" permission, so the groups are expected to be different. But I do still appear to be missing a permission that she has: "floppy". There doesn't appear to be an entry for that in users- admin (unless it has an unrelated name ...). tris...@tinygod4:~$ cat /etc/polkit-1/localauthority.conf.d/51-ubuntu-admin.conf [Configuration] AdminIdentities=unix-group:admin tris...@tinygod4:~$ groups tristan adm dialout fax cdrom tape audio dip video plugdev fuse lpadmin netdev admin sambashare tris...@tinygod4:~$ sudo su kateryna [sudo] password for tristan: kater...@tinygod4:/home/tristan$ groups kateryna adm dialout fax cdrom floppy tape audio dip video plugdev fuse netdev sambashare kater...@tinygod4:/home/tristan$ exit exit tris...@tinygod4:~$ I can use Update Manager as myself just fine. ** Changed in: gnome-system-tools (Ubuntu) Status: Incomplete => New -- User account lost permissions after Karmic upgrade, breaking all audio https://bugs.launchpad.net/bugs/477832 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
