    Default upgrade broke server :Unable to connect to the MTA

    I upgraded zcs from 5.0.2 to 6.0.4 by running the latest installer. The upgrade seemed to go without error and I was impressed with the installer's ability to find things previously installed during the upgrade. However, I and getting the following "Unable to connect to MTA" error on the upgraded system. No emails in or out after the upgrade.

    So the error seems to be obvious from the attached zimbra.log file, no MTA service running. In fact, none of the previous services appear to be running after the upgrade like anti-spam, anti-virus, etc. Although, Apache is up and I can log into zimbra over http. You can see were I started the upgrade at 14:10. I reverted to a backup for now.

    I forgot to mention that the system is 32-bit Ubuntu Server 8.0.4 LTS with all the latest updates. The installer came from here:

    http://h.yimg.com/lo/downloads/6.0.4...1214184037.tgz

    Your file as shown above is incorrect:
    Code:
    root@zimbra:/home/mtsuser# cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 zimbra.microtechcorp.com zimbra
173.12.26.121 zimbra.microtechcorp.com mail.microtechcorp.com
    It should contain only the following (as per the Quick Start Installation Guide and numerous forum threads):

    Code:
    127.0.0.1 localhost.localdomain localhost
173.12.26.121 zimbra.microtechcorp.com zimbra

    I changed it, then reboot the system. I'm still getting the same error.

    mtsuser@zimbra:~$ cat /etc/hosts

    Here is a cat of my startup.log in /opt/zimbra/log/. It looks like mta is failing to start. Not sure why?

    Shut down Zimbra and run this (as root) then restart Zimbra:

    Code:
    /opt/zimbra/libexec/zmfixperms

    I ran /opt/zimbra/libexec/zmfixperms, then rebooted the system. MTA still does not start. I noticed that logger and logswatch also do not start? The installer did complain about sysstat not being installed, so I quit the install when prompted and did an apt-get install sysstat, then rerun the installer. Not sure if relevant? My latest tail on startup.log, look like the zmfixperms did not resolve the problem.

    Have a look in the log files and see if there's any other errors in there, post them if there is.
