(SOLVED) Error moving from Ubuntu 14.04 to 16.04: It should be impossible to reach this statement.

[rdlarkin]

I am trying to migrate my Zimbra server from one running Ubuntu 14.04 to 16.04. I have followed the instructions found here: https://wiki.zimbra.com/wiki/How_to_mov ... her_server

Everything works up until the point where I am running the final install.sh script at which point the following occurs:

The contents of the log file created are simply:

COMMAND: ldap start

I am unable to find anything referencing this error with a resolution, does anyone have any ideas?

I had a similar problem when I tried to move my 8.7.11 instance from ubuntu-12.04 to ubuntu-16.04.

I created my new 16.04 machine and installed the correct version of zcs on it. Then I stopped zimbra and mounted my existing installation of the same version at /opt/zimbra, then tried to run ./install.sh.

I got a similar error, but in my case, the message was more specific in mentioning some missing perl:

Code: Select all

> sudo ./install.sh

I was able to resolve this be reinstalling all of the zimbra perl modules into my old zimbra installation:

Code: Select all

for pkg in $(dpkg -l | grep zimbra | grep perl | awk '{print $2}'); do sudo apt-get install --reinstall $pkg; done

After this, running ./install.sh succeeded successfully, detecting my previous install and "upgrading" it to the same version.

Thank you wryfi, that code worked and fixed the issue. I should note that if using rsync to copy the data the code must be run after the final rsync, any further rsync will require you to run the code provided by wryfi again.

A massive thank you wryfi. I was doing the same upgrade (8.7.11 from ubuntu-12.04 to ubuntu-16.04) which almost came to a sad end until I saw your post here. You saved a long and mission critical upgrade.

Thank you very much for taking the time to post your solution!
