Comment 29 for bug 40795

After setting a password for the ubuntu user, I can create a printer in the web interface (I just get the usual 'unauthorized' log messages, but they are bogus -- cupsd always seems to try unauthorized access first, and then requests credentials if that fails; it happens all the time without a visible negative impact).

After the printer is created in the web interface, I can exercise ubuntu's lpadmin group powers with cupsenable/cupsdisable, can use gnome-cups-manager to print a test page, and so on.

So only creating a printer fails in the live system, the log messages point to some problem while copying the PPD file.

Till, do you have an idea about that?
