How to fix missing Advisory Information in Enterprise Linux (EL) based Local Repository

There are two ways to fix missing advisory information in your EL-based local repository:

Pre-requisite:  Please check if the local repository is advisory based using the following two commands:

For Security Advisories

dnf updateinfo list security all

For Bug Fixes

dnf updateinfo list bugfixes all

Automatic: Using the yum-plugin-security plugin

To use the yum-plugin-security plugin to automatically download and add advisory information to your local repository, follow these steps:

1. Install the yum-plugin-security plugin:

dnf install yum-plugin-security

2. Enable the yum-plugin-security plugin in your /etc/yum.conf file:

plugins=security

3. Update your local repository:

dnf clean all
dnf update

The yum-plugin-security plugin will automatically download the latest advisory information from the Red Hat website and add it to your local repository.
