Which packages to use for Debian and Kolab 3.1 ???

[Karma Kolabor]

Hi,

ok, I have to admit that I am not a kolab follower from hour one and
just recently started to take a closer look as 3.1 seems to come near
to what I would like to use.

The effect of not being involved deeply into the kolab history is:
total dis-orientation about which packages to choose for installation
on a Debian 7 system.

Unfortunately following the reference documentation at
http://docs.kolab.org/installation-guide/debian.html

does NOT work.

Question: which package source should I use to get a working kolab 3.1
on Debian Wheezy?

Thanks!
Have a nice day,
Karma
