Symptoms

  • Upgrade to Plesk Obsidian fails with the following dependency error if postfix-perl-scripts is installed:

    PLESK_ERROR: Exception: Failed to solve dependencies:
    2:postfix-perl-scripts-2.10.1-7.el7.x86_64 requires postfix = 2:2.10.1-7.el7
    Error: Package: 2:postfix-perl-scripts-2.10.1-7.el7.x86_64 (base)
    Requires: postfix = 2:2.10.1-7.el7
    Installed: 2:postfix-3.4.5-2.centos.7+p18.0.19.0+t190904.1310.x86_64 (@PLESK_18_0_19-dist)
    postfix = 2:3.4.5-2.centos.7+p18.0.19.0+t190904.1310
    Available: 2:postfix-2.10.1-7.el7.x86_64 (base)
    postfix = 2:2.10.1-7.el7

  • In Plesk Obsidian, it's not possible to install additional Postfix packages such as postfix-perl-scripts.

Cause

This is considered as a Plesk bug with ID #PPPM-11129 which will be fixed in future Plesk updates.

Resolution

Note: Currently it is not possible to use additional Postfix libraries/packages in Plesk Obsidian.

As a temporary workaround, apply the following solution:

  1. Connect to the server via SSH

  2. Remove postfix-perl-scripts package:

    # yum remove postfix-perl-scripts

  3. Proceed with upgrade:

    # plesk installer

    While trying the same Obsidian upgrade (Plesk 17.8 -> Plesk 18), I experienced the same dependency issue with "postfix = 2:2.10.1-7.el7".

    In my case, the troubling package is "2:postfix-sysvinit-2.10.1-7.e17.noarch": it will not upgrade, citing the same dependency. As a result, it will block the whole upgrade.

    Successfully applied the resolution:

    1. Connect via SSH

    2. Run "yum remove postfix-sysvinit"

    3. Run "plesk installer"

     

    Thank you!  :-)

    When will this be fixed? I am afraid to apply a "temporary workaround".

    Tobias, right now we don't have ETA.

    Can I safely remove "postfix-perl-scripts" or "postfix-sysvinit"?

    Were they installed from a previous Plesk version or Plesk extension?

    I have the problem on two different servers and I don't think I installed them myself.

    Hello Tobias Buschor

    No issues should be caused by a workaround in question.
