No, nagios3 has never been on this system before. I've tested on another clean system and the same error occurs.
You should be able to reproduce this easily: apt-get purge nagios* apt-get install nagios3-core nagios3-core expects nagios3-cgi to be setup. You need to add the following line to the nagios3-core section of debian/control: Pre-Depends: nagios3-cgi ** Changed in: nagios3 (Ubuntu) Status: Incomplete => New -- nagios3-common and nagios3-core : grep: /etc/nagios3/cgi.cfg: No such file or directory https://bugs.launchpad.net/bugs/615810 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
