@ all - any update on this? I'm trying to install the latest version (zcs-NETWORK-6.0.10 for Ubuntu 10.04 64) on Ubuntu 10.10 64. I'm having the very same issue with the file /etc/hosts/. How can I fix that? I was also trying to edit the file like here (diggleby Blog Archive how to fix zimbra error please fix /etc/hosts file), but nothing happened.

@ ipguru99 - what exactly did you edit in the file utilfunc.sh?
