Security Updates Overview

This section describes how to query and install HCE security updates using yum or dnf.

The support for yum and dnf depends on the OS version. This section uses yum as an example.

As a substitute for yum, dnf delivers better performance. The methods for using dnf and yum are the same.

  • HCE 2.0 and later support both yum and dnf.
  • Versions earlier than HCE 2.0 support only yum.
