Before we can fix the issue of games, we need to fix the repos you show listed.
[f0r3v3r50f7@openmandriva-x8664 ~]$ dnf repolist
repo id repo name
rolling-i686 OpenMandriva Rolling - i686
rolling-x86_64 OpenMandriva Rolling - x86_64
This one needs to go away. Please find it in Discover and uncheck the box.
rolling-i686 OpenMandriva Rolling - i686
Once this is done, we need to open the repo picker in OM-Welcome.
I have Rolling, but I don’t know which you have. Regardless, you are going to need to make sure you have these repos selected.
The OpenMandriva Repo Picker is the only safe place to add repos for the average user.
