I can confirm the same error as John Doe's error_log at http://librarian.launchpad.net/2419144/error_log
I tried the command "sudo gnome-cups-manager" with the same output. I even tried creating the "/var/cache/cups/ppds.dat" file with "sudo touch /var/cache/cups/ppds.dat" and it still reports: [cups-driverd] Unable to write "/var/cache/cups/ppds.dat" - Permission denied E [01/May/2006:00:33:36 +0000] CUPS-Add-Modify-Printer: Unauthorized -- [6.06 Beta - Live CD] Adding a printer silently fails. https://launchpad.net/bugs/40795 -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
