How to install EPEL Repository Rocky Linux? [SOLVED]


Written by - Omer Cakmak

EPEL (Extra Packages for Enterprise Linux) is the repository that provides a number of additional packages for RHEL (Rocky Linux, AlmaLinux, CentOS and others) from Fedora sources. The packages included in this repository were developed by the Fedora developer community group.

There are 2 different methods to add the EPEL repository. The first of these is to add the EPEL repository by installing the epel-release package from the Rocky Linux repositories. The second is to manually install the epel-release.rpm package on the system. Let's started.

 

Method-1: Package Installation From Repository

View the repositories in the system before installing the package from the repository:

[foc@rocky9 ~]$ sudo dnf repolist
repo id                     repo name
appstream                   Rocky Linux 9 - AppStream
baseos                      Rocky Linux 9 - BaseOS
extras                      Rocky Linux 9 - Extras

Standard Rocky Linux repositories are available. To add the EPEL repo to Rocky Linux, it is necessary to install the following package:

[foc@rocky9 ~]$ sudo dnf install epel-release

Many EPEL packages require the CodeReady Builder (CRB) repository.
It is recommended that you run /usr/bin/crb enable to enable the CRB repository.

  Verifying        : epel-release-9-4.el9.noarch                    1/1 

Installed:
  epel-release-9-4.el9.noarch                                           

Complete!

Pull the repository list after package installation:

[foc@rocky9 ~]$ sudo dnf repolist
repo id           repo name
appstream         Rocky Linux 9 - AppStream
baseos            Rocky Linux 9 - BaseOS
epel              Extra Packages for Enterprise Linux 9 - x86_64
extras            Rocky Linux 9 - Extras

You can see that the "Extra Packages for Enterprise Linux 9" repository is active on the system.

 

Method-2: Adding a Repository by installing EPEL RPM package

For the EPEL repository on RHEL-based systems, there may be systems that do not keep RPM packages in their repositories. In fact, many distributions did not have this package in their repositories before. The RPM package needs to be manually downloaded and installed on the system.

View package repositories before installation:

[foc@rocky9 ~]$ sudo dnf repolist
repo id                     repo name
appstream                   Rocky Linux 9 - AppStream
baseos                      Rocky Linux 9 - BaseOS
extras                      Rocky Linux 9 - Extras

Below is the RPM package link for 3 different RHEL versions:

Since we will add the EPEL repository to Rocky Linux 9, we install the RPM package to the system using the first link:

[foc@rocky9 ~]$ sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
Rocky Linux 9 - BaseOS                  3.4 kB/s | 3.6 kB     00:01    
Rocky Linux 9 - BaseOS                  2.0 MB/s | 1.7 MB     00:00    
Rocky Linux 9 - AppStream               8.7 kB/s | 4.1 kB     00:00    
Rocky Linux 9 - AppStream               2.3 MB/s | 6.4 MB     00:02    
Rocky Linux 9 - Extras                  6.6 kB/s | 2.9 kB     00:00    
Rocky Linux 9 - Extras                  7.5 kB/s | 6.6 kB     00:00    
epel-release-latest-9.noarch.rpm         29 kB/s |  18 kB     00:00

Complete!

After installation the repositories are:

[foc@rocky9 ~]$ sudo dnf repolist
repo id           repo name
appstream         Rocky Linux 9 - AppStream
baseos            Rocky Linux 9 - BaseOS
epel              Extra Packages for Enterprise Linux 9 - x86_64
extras            Rocky Linux 9 - Extras

The ".repo" files related to the EPEL repository are located under the /etc/yum.repos.d/ directory. You can do edit it manually from here:

[foc@rocky9 ~]$ ls -la /etc/yum.repos.d/epel*
-rw-r--r--. 1 root root 1453 Aug 10 16:11 /etc/yum.repos.d/epel.repo
-rw-r--r--. 1 root root 1552 Aug 10 16:11 /etc/yum.repos.d/epel-testing.repo

The epel-release package version in Rocky Linux 8:

[foc@rockylinux8 ~]$ sudo dnf list installed | grep epel-release
epel-release.noarch 8-18.el8 @extras

Package version in Rocky Linux 9:

[foc@rocky9 ~]$ sudo dnf list installed | grep epel-release
epel-release.noarch 9-4.el9 @extras

 

How to Enable EPEL Repo

If the EPEL repo is disabled in Rocky Linux, you can enable it with the following command:

[foc@rockylinux8 ~]$ sudo dnf config-manager --set-enabled epel

You can see EPEL in the repo list:

[foc@rocky9 ~]$ sudo dnf repolist
repo id           repo name
appstream         Rocky Linux 9 - AppStream
baseos            Rocky Linux 9 - BaseOS
epel              Extra Packages for Enterprise Linux 9 - x86_64

 

How to Disable EPEL Repo

To disable the EPEL repository:

[foc@rocky9 ~]$ sudo dnf config-manager --set-disabled epel

You can see that the EPEL repository is disabled:

[foc@rocky9 ~]$ sudo dnf repolist
repo id                     repo name
appstream                   Rocky Linux 9 - AppStream
baseos                      Rocky Linux 9 - BaseOS
extras                      Rocky Linux 9 - Extras

After this step, the ".repo" files under the /etc/yum.repos.d directory are not deleted, only the "enabled" value in it is changed to 0 for all the respective repos.
