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

Context

JetPatch patches at the Errata level (see explanation why).  Therefore, it is required that clients are configured to pull the necessary advisory information from their assigned repo.  

You can make sure your repository is advisory based by using the following three commands:

For Security Advisories

dnf updateinfo list security all

For Bug Fixes

dnf updateinfo list bugfixes all

For Enhancements

dnf updateinfo list enhancements 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.
