I have a perfectly working zimbra 5.0.16 installation on Ubuntu 8.04 LTS 32bit. I am trying to upgrade to 5.0.18 but I am stuck at
Code:
Installing packages

    zimbra-core......zimbra-core_5.0.18_GA_3011.UBUNTU8_i386.deb...
The installer ist just hanging forever.

Checking the processes there is no upgrade process running except
Code:
/bin/bash ./install.sh
Any idea?
