The problem is that other daemon grab this port before cupsd gets a chance, typcally rpc. See: https://bugzilla.redhat.com/show_bug.cgi?id=103401
Work around: lsof -i :631 stop or kill the process, restart cups long term solution: I guess distros should ensure processes use different port number. Note: The same problem happens on a workstation that try to browse for remote printers (cupsctl --remote-printers), you don't get an error, but "lpstat -a" doesn't show remote printers. ** Bug watch added: Red Hat Bugzilla #103401 https://bugzilla.redhat.com/show_bug.cgi?id=103401 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/304393 Title: cups: 127.0.0.1:631 - Address already in use.
