This I can help with. I'm assuming you are running CentOS, not RHEL. <br>
CentOS just released their el8.2 release. You are/were running a kernel <br>
from the el8.1 release (denoted by the el8_1 release tag). When CentOS <br>
went from el8.1 --> el8.2, all the old el8.1 packages (including your <br>
kernel) were moved to the vault and are no longer available by default, <br>
hence why yum can not find the package to reinstall. To make them <br>
available again, you would need to enable the CentOS vault repo in your <br>
yum configs.<br>
