Hi,

first of all I need to say I never used or installed nagios before. 
So it's a fresh and clean install of nagios3 for me.
I personally think that the postinst script expects things to be there
which were set up by previous versions of nagios3.
So, in my opinion, upgrading to 3.2.0 is no problem, but a clean install
of 3.2.0 is.

here goes:

# apt-get install nagios3-cgi

After editing /var/lib/dpkg/info/nagios3-cgi.postinst to get some debug
info:
#if [ -n "$NAG3DEBUG" ]; then
  echo "now debugging $0 $@"
  set -x
#fi


I get this:

As you can see, the line "db_cmd 'GET nagios3/httpd'" fails getting any
configuration value.
That's ok, because I cannot find 'SET nagios3/httpd' or whatever necessary
in the pre/postinst scripts.
I believe that in version 3.0.6 the missing 'SET nagios3/httpd' were
there, but I'm not sure.

I hope I've provided sufficient information.
If you need more info, just ask.
