Jimbo,
Hi mate, hope you had a good holiday.
Try upgrading to 4.5.7/8/9/10 and then try again to finally upgrade to 5.0.
I must say I had to run the ./install.sh script numerous times and rebooted my server about three times in between.
Here is what I would check, assuming you are running ~RHEL4:
Download your specific next upgrade Zimbra Version from:
SourceForge.net: Files
Backup your zcs install:
Code:
rsync -ra /opt/zimbra /backup/ --progress
Unzip and run the installer for your downloaded Zimbra Version.
!!
Remove any variables in the /root/.bashrc file
Logout as root and then back in again and ensure no $PERLLIB etc variables are set
!!
Run the instructions in the root shell from
here
Now try ./install.sh again...if it fails..reboot and try runig ./install.sh again ... repeat as necessary it took me three reboots.
Make note each time you try to upgrade as to the version your system is upgrading from...
Good luck
