[cups] Difficulty in Adding a printer

Wed Jan 14 13:40:40 PST 2015

Alan,

This looks like you have multiple cupsd processes running, and/or a configuration problem that is preventing the CGI programs from connecting to the domain socket (which prevents the authentication credentials from being passed from the web interface to cupsd...)

I'd start with a bug report to the Debian folks...
