Issue Postfix not working after installing Plesk Obsidian on Red Hat 8

[rogonl]

I'm trying to setup the latest Plesk Obsidian release on a Red Hat 8 server, but it seems the installation of postfix seems to fail (see details below). I guess this happens because of the fact that it automatically tries to install CentOS packages and not the standard Red Hat 8 packages. How can I get this fixed and make sure this problem doesn't reoccur after the next upgrade?

Kind regards, Ronald van Gogh

Yes, we install our postfix 2: 3.4.8, which is newer than the system postfix 2: 3.3.1-9.el8
CentOS is in the package name because the build is on CentOS 8, but the packages are common for CentOS and RHEL.

Developers have checked this issue and confirmed. The bugreport PPP-48637 has been submitted.

As a possible workaround, you can apply following patch to /etc/postfix/main.cf file:

+shlib_directory = no
-inet_interfaces = all
-shlib_directory = /usr/lib64/postfix

Hi Igor,

I received first a mail from you to register a report for this. Is this still necessary as I see now that already a bugreport has been created?
Secondly, I know that installing CentOS packages on RHEL systems normally works, but I guess you need to be careful with this when regular packages are already being used from the standard repositories and especially when additional repositories like EPEL are being used as well.
Finally, I did bypass the problem now by creating the additional directory /usr/lib64/postfix manually on the server including the libraries I copied from another server.

1. The report was already submitted, you should do nothing.
2. Agree.
3. It's better to use the patch above.

Thanks. Is there a way I can track the status of this bugreport PPP-48637?
