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 Desktop Packages, which is subscribed to system-config-printer in Ubuntu. https://bugs.launchpad.net/bugs/387970 Title: cups asks for root password if user is not member of lpadmin group Status in “system-config-printer” package in Ubuntu: Confirmed Bug description: Binary package hint: system-config-printer-gnome When I add a printer using "system-config-printer.py" (system - administration - printing - new), it asks me for a root password instead of a sudo password.
