Resolved ERROR: 'NoneType' object has no attribute 'run_sack'

New Pleskian
Hi,
When I update the system, the package list is not displayed with the following error.

ERROR: 'NoneType' object has no attribute 'run_sack' 2021-08-21 14:45:27 ERROR: Exited with returncode 1.

Is there something wrong with the Python version?

# grep run_sack -r /lib/*
/lib/python3.6/site-packages/dnf/plugin.py: def run_sack(self):
/lib/python3.6/site-packages/dnf/base.py: self._plugins.run_sack()

Also seeing this here whenever Plesk does its auto update check. If I run it manually, I get the same thing:
plesk sbin pum --list --repo-info --json

A bunch of DEBUG output lines, then ends with:

ERROR: 'NoneType' object has no attribute 'run_sack'
ERROR: Exited with returncode 1.

This prevents Plesk auto update from proceeding.
