Upgrade RHEL 7.9 - 8.4: LEAPP thows problem with missing yum-plugins, but they are installed.

Hello,

i want to upgrade S4HANA from 2019 to 2021 and therefore first need to upgrade RHEL from 7.9 to 8.4.
I#m at the start of the process, with leapp-utility preupgrade run.

In that process it throws the following problem:

Risk Factor: high (inhibitor)
Title: Required YUM plugins are not being loaded.
Summary: The following YUM plugins are not being loaded:
- product-id
- subscription-manager
Remediation: [hint] If you have yum plugins globally disabled, please enable them by editing the /etc/yum.conf. Individually, the YUM plugins can be enabled in their corresponding configurations found at: /etc/yum/pluginconf.d
[command] bash -c "sed -i 's/^plugins=0/plugins=1/' '/etc/yum.conf'; sed -i 's/^enabled=0/enabled=1/' '/etc/yum/pluginconf.d/subscription-manager.conf'; sed -i 's/^enabled=0/enabled=1/' '/etc/yum/pluginconf.d/product-id.conf'"

but yum has those already installed, as seen in:

[root@hana2dev3 leapp]# yum search product-id

Geladene Plugins: langpacks, product-id, search-disabled-repos, subscription-manager

Where's the problem, what to do?
