Hi Alessandro,

You will need to provide more information for me to be able to help, 
like the errors you received.

As a general rule, try not to mix elrepo and rpmfusion repos, or if you 
have to, do so carefully and manage any conflicts manually.

You can usually tell which point release kernel series a kmod is built 
for by the tag in their release (e.g, el8.2 packages will have the 
elrepo.el8_2 release tag), so you can ensure you are installing / 
updating the correct package for your system.

Regards,

Phil
