Resolved Centos 8.0 not updating : conflicting requests

[JulianDot]

Everything else is working fine for the moment. Those are test servers ( trial licenses) so is not that important to have that fixed now.

I have 2 different Centos 8.0 with latest Plesk:

OS	CentOS Linux 8.0.1905 (Core)
Product	Plesk Obsidian Version 18.0.25 Update #2,

LXC containers.

On both the button "check for updates" from interface trigger an error in systemupdatestool.log :

 Problem: conflicting requests
  - nothing provides module(nginx) needed by module php:7.2:8010020191114034540:2430b045-0.x86_64

The output of :

dnf list --installed '*python*'

Modular dependency problem:

This is possible if the "PHP from OS vendor" component is not selected in the Plesk installer, but the php package is installed on the system. You can check this by the output of the rpm -q php commands - there will be a version. rpm -q psa-php-configurator - will not find anything.
If this is true and you do not need system php - you can remove packages, if necessary - you can enable it in Plesk installer as "PHP from OS vendor" component.
Also, you can show me output of dnf module list --enabled just in case.

AFTER enabling "PHP from OS vendor", all the below output is different. But i need to wait a bit in order to try to update again.

BEFORE: i have enabled only PHP 7.4 and 7.3 , and NO "PHP from OS vendor"
The below is the output without "PHP from OS vendor".

[root@bok8 ~]# rpm -q php
package php is not installed

[root@bok8 ~]# rpm -q psa-php-configurator
package psa-php-configurator is not installed

[root@bok8 ~]# dnf module list --enabled

AFTER enabling "PHP from OS vendor", No errors.

Still no updates , even if i am on Centos 8.0 and i am expecting an update to Centos 8.1
But that is another story

You can remove the warning using

# dnf module disable php
