Zenoss core 4.2.5 on ubuntu 14.04 server using virtualbox

I am trying to installZenoss core 4.2.5 on ubuntu 14.04 server using virtualbox.I have followed the following link.

https://github.com/hydruid/zenoss/blob/master/core-autodeploy/4.2.5/zo425_ubuntu-debian.sh

on checking the status of zenoss ,i am getting that zopectl is not running,i tried running it individually (zopectl start),but in vain.

I even wanted to clarify if zenoss core 4.2.5 can be installed on ubuntu 14.04 server using virtualbox or it has to be done on centOS.I would be really glad if someone could provideproper installation procedure onubuntu 14.04 .
