    cd /tmp
  • extract the installation files and execute the installer with root privileges:

    tar xvfz zcs-NETWORK-8.7.11_GA_1854.UBUNTU14_64.20170531151956.tgz
    cd zcs-NETWORK-8.7.11_GA_1854.UBUNTU14_64.20170531151956
    sudo -s

    When you are asked to verify database store integrity, answer No:

2. Upgrade Ubuntu-OS from 14.04 to 16.04

Currently, the OS upgrade to Ubuntu 16.04 has to be done using a workaround, since as of right now, upgrading to 16.04 breaks the current Zimbra installation when following the officially suggested way, as reported in Bug 107436.

Check if you have enough space available in /boot/ partition for a new kernel and in / to download and install the necessary packages for Ubuntu 16.04.

  • Stop all Zimbra-services as user zimbra

    zmcontrol stop
  • When all services are stopped logout as user zimbra

  • Now create a file called /etc/update-manager/release-upgrades.d/allow-thirdparty.cfg with root privileges:

    sudo -s
    vi /etc/update-manager/release-upgrades.d/allow-thirdparty.cfg
  • and enter this content

  • save the file and perform the OS-upgrade via:

  • When you are asked if you want to replace config files that have been changed, choose N to keep the current ones.

  • When the release has been upgraded, the server is rebooted. Check the current Ubuntu-version after the reboot has been completed:

    cat /etc/issue
    Ubuntu 16.04.3 LTS \n \l
  • In case not all zimbra services have been started completely after the reboot, please perform a service restart

    sudo su - zimbra
    zmcontrol restart
  • After all zimbra services are up and running again, Zimbra 8.7.11 on Ubuntu 16.04 is now ready.
