With the recent announcement by CentOS 8 regarding the switch from CentOS 8 to CentOS Stream, this commonly used Linux distribution is being relegated to a mid-stage development version of RHEL. In essence, CentOS 8 becomes an early rolling-release distro for RHEL. As CentOS moves from being a follow-up distribution to the stable version of RedHat, to be, in effect, a prerelease version of RHEL, many users are looking for alternatives to replace their current operating systems with a long-term stable platform apart from RHEL and IBM who owns RedHat.

What’s an ‘EPEL repository’?
The EPEL repository is managed by the EPEL group
, which is a Special Interest Group within the Fedora Project. The ‘EPEL’

There are numerous operating systems to choose from; however one of the most popular, most stable, and highly supported OSes is CentOS. A combination of excellent features, rock-solid performance stability, and the backing of enterprise-focused institutions such as Red Hat and Fedora have led to CentOS becoming a mainstay OS that administrators can count on.
