Prerequisite

  • Rocky Linux Operating System Installed
  • Sudo user/Root user privilege required
  • Access to internet required

 

1.  Install using DNF Package Manager

In this method, we will install the epel-release package using the dnf package manager which is by default present in Rocky Linux system. To do so, connect to your Linux machine and switch to the sudo/root user. I am using root user. Next, check if epel repository is already installed in the system by using below command. As you see in the output, currently only standard Rocky Linux repositories  are installed.

[[email protected] ~]# dnf repolist
repo id    repo name
appstream  Rocky Linux 9 - AppStream
baseos     Rocky Linux 9 - BaseOS
extras     Rocky Linux 9 - Extras

 

NOTE:

If you use sudo user, add sudo in front of the commands. For example,
[[email protected] ~]# sudo dnf repolist

 

Next, we will install the epel-release package which will add the epel repository in the system. To do so, use below command.

[[email protected] ~]# dnf install epel-release
