And what now?!

You appear to be installing Zimbra on Debian 6, is that correct? If that's the case then you're using the wrong Debian version, Debian 6 is not supported and you should install Zimbra on the correct version - that would be Debian 5.

Yes, I am running Debian 6 indeed.
Is Debian 6 support expected in the near future?

Try Ubuntu 10 LTS, it work well in it
