I followed "How To Install Zimbra Collaboration Suite (ZCS) On Ubuntu" here
(thanx for providing this howto!).
Everything goes great until halfway step 3. After I answer 'yes' to 'The system will be modified. Continue?' I get this error :
zimbra-core_4.5.3_GA_733.DEBIAN3.1_i386.deb installation failed
I downloaded the most recent Debian package from the Zimbra Sourceforge page (not corrupted). The setup is a standard clean Debian Sarge install, with correct MX-record.
I don't know where to go from this error, I couln't find a solution on the Zimbra forums or here.
Did anyone succeed installing Zimbra on Debian Sarge? Any thoughts on how I can solve this?
