as mentioned in #22; I had this issue when I messed up accounts and groups. It prompts (with an ugly prompt) for authentication if you're not in the lpadmin group. When I set 'sudo usermod -aG lpadmin myusername' it worked flawlessly afterwards.
The bug is that it does not detect more gracefully if you are not a member of the lpadmin group. ** Summary changed: - cups asks for root password + cups asks for root password if user is not member of lpadmin group -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/387970 Title: cups asks for root password if user is not member of lpadmin group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/387970/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
