Bug 2219796

Description of problem:

The value of releasever is automatically picked up as the OS Version of 9.2 in "/etc/yum/vars" on creating an Azure RHEL 9.2 VM. Due to this, the metalink in the epel.repo file in "/etc/yum.repos.d" points to https://mirrors.fedoraproject.org/metalink?repo=epel-9.2&arch=x86_64&infra=$infra&content=$contentdir which is invalid and gives a 404 error code.
The only applicable value for substitution of releasever in the metalink is 9.
This issue was reported in a lower version and reported to have an interim fix of hardcoding the releasever variable (https://bugzilla.redhat.com/show_bug.cgi?id=1969500)


Version-Release number of selected component (if applicable):


How reproducible: 100%


Steps to Reproduce:
1. Create an Azure VM with OS Linux (RHEL 9.2)
2. Confirm value of releasever in "/etc/yum/vars" has been auto populated with 9.2
3. # sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y


Actual results:

Extra Packages for Enterprise Linux 9.2 - x86_64                                                                              82 kB/s | 109 kB     00:01

Expected results:

The value in metalink should be populated with 9 and running "sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y" should allow the user to install the epel-release package.

Workaround - sed -i 's/$releasever/9/g' /etc/yum.repos.d/epel.repo
