my system is currently a Dapper release (with latest updates installed). It has been upgraded from breezy.
I have the same issues when trying to add a printer as a user: access_log: localhost - - [09/Aug/2006:10:57:59 +0200] "POST /admin/ HTTP/1.1" 401 368 CUPS-Add-Modify-Printer successful-ok localhost - root [09/Aug/2006:10:57:59 +0200] "POST /admin/ HTTP/1.1" 200 368 CUPS-Add-Modify-Printer client-error-not-possible error_log: E [09/Aug/2006:10:57:59 +0200] CUPS-Add-Modify-Printer: Unauthorized and when launching the gnome-cups-manager with sudo: ** (gnome-cups-add:5579): WARNING **: IPP request failed with status 1028 Existing printers work fine. I have tried the same on another machine with the same 'history' and it works on that one, eventhough I get the Unauthorized message! btw: on both machines I get these in syslog: Aug 9 10:48:17 mini hp: unable to open /var/run/hplip/hpiod.port: No such file or directory: prnt/hpijs/hplip_api.c 84 Aug 9 10:48:17 mini hp: unable to connect hpiod socket 50000: Connection refused: prnt/hpijs/hplip_api.c 703 Aug 9 10:48:17 mini hp: unable to send ProbeDevices: Broken pipe -- cannot write /var/cache/cups/ppds.dat on live system https://launchpad.net/bugs/40795 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
