One of our customers recently ran into the following error while attempting to install OpenStack Yoga release on CentOS Stream 8 Server. In fact, the error was noted while trying to tun the following command to install Keystone:

EPEL, short for Extra Packages for Enterprise Linux is a community-based, open-source repository project. It offers a high quality set of packages for Enterprise Linux including CentOS, Rocky Linux, RHEL, and Alma Linux.

The Unknown repo EPEL error often pops up when the system is unable to find the EPEL repository. The error may also be due to a disabled or incorrectly configured EPEL repository in the system. Additionally, the error may also be due to connectivity issues that are preventing the system from accessing the repository.

We can resolve the Error Unknown repo epel by installing EPEL repo as seen below:

1. To begin with, we have to run this command in order to install EPEL repo on CentOS Stream 8:

   # dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

   Or,
   # dnf config-manager --set-enabled PowerTools
# dnf install epel-release
2. Next, we have to update the software packages with this command:

   # dnf update
3. Finally, ensure EPEL repo is enabled as seen below:
