If, by helping you, are we enabling you to cheat? If the answer is yes, you had better stop reading this and figure out your
issue on your own (by reading the apt docs...hint...hint)


What OS/version is this?

-----------------------------
If the OS is Debian Lenny (This may/may not work in Ubuntu):
-----------------------------

Fist find which nagios packages are installed. Install apt-show-versions.  I recommend using aptitude has it has greater
package dependency handling abilities and saftey guards.


[15:27:28 root at jenna:~]# aptitude install apt-show-versions


Second, invoke apt-show-versions and parse the output using grep.

[15:29:28 root at jenna:~]# apt-show-versions  | grep nagios
nagios-images/lenny uptodate 0.4
nagios-nrpe-plugin/lenny uptodate 2.12-1
nagios-plugins/lenny uptodate 1.4.12-5
nagios-plugins-basic/lenny uptodate 1.4.12-5
nagios-plugins-standard/lenny uptodate 1.4.12-5
nagios3/lenny uptodate 3.0.6-4~lenny2
nagios3-common/lenny uptodate 3.0.6-4~lenny2
nagios3-doc/lenny uptodate 3.0.6-4~lenny2
[15:29:33 root at jenna:~]#


The first string is the package name to use as an argument to `aptitude remove --purge`.  I recommend you start from scratch
and remove ALL nagios packages to help quell confusion.

If I wanted to only remove the nagios core package(s) (and purge configuration files) I would invoke aptitude like this:

[15:29:33 root at jenna:~]# aptitude remove --purge nagios3 nagios3-common

If I wanted to save the configuration files, I would omit the --purge switch.

If, you are like me and are short tempered, you can invoke aptitude with more than one task. Such as the following.

[15:29:33 root at jenna:~]# aptitude remove --purge nagios3 nagios3-common nagios2+

This command will remove (and purge) nagios3 and nagios3-common. Then it will install nagios2 thuns accomplishing a
downgrade.  Obviously, this command isn't what you want, but I decided to show it for informational purposes.



hope this helps.
