Installation of printer driver freezes shortly after authentication
Status in system-config-printer package in Ubuntu:
Searched for printers on Dash, opened it and added printer, chose network
printer, my printer was displayed so clicked it. Driver download box opened
and I started it. After authentication, the box froze, progress indicator
stopped moving, box would not respond to CANCEL or X(for quit).
Tried it three times, no difference.
