Install DKMS on Rhel8.8

Question

Newbie here.

I want to install dkms for my RHEL 8.8. I learnt that its not supported on RHEL and has to be fetched via epel.

I ran the below step

yum install /home/abhi/Downloads/epel-release-latest-8.noarch.rpm 

and got success for it.

But ran into below errors

[root@localhost src]# sudo yum install dkms

Any idea what's going wrong or how to fix ?
