How can I regenerate the default '/etc/' config files? I've removed `nagios3` with `apt-get remove nagios3` and then removed the files in by using the command `sudo rm -R /etc/nagios` Now when I run `apt-get install nagios3` the config files (`/etc/nagios3/`) are not present. How can I regenerate them? This box is on Ubuntu 10.04.

Purge `nagios3`. Then reinstall. That will probably work.

apt-get purge nagios3
apt-get install nagios3

The purge will get rid of the config files, which the system didn't delete initially, and so thought were still installed. If purging `nagios3` is not an option, then it will be a little more complicated. If that is the case, leave a comment.
