Redhat Attaching subscriptoin manager

I'm getting the following error when trying to install a package: There is no repository enabled in /etc/yum.repos.d.

I realized that to have access to the redhat repositories I need to have an account on the site, I did that and after that I linked it to my terminal with the commands:

Below is what helped to get over this issue

Un-register the system :

sudo subscription-manager remove --all

sudo subscription-manager unregister

sudo subscription-manager clean

Re-register the system :

sudo subscription-manager register

sudo subscription-manager refresh

Search for the Pool ID :

sudo subscription-manager list --available

Attach the subscription :

sudo subscription-manager attach --pool=<Pool-ID>
