Package management is an important function in RHEL 8 systems. From the day a well-maintained system comes online, to the day it’s decommissioned, packages are installed, removed and updated on a regular basis. In this hands-on lab, we will install and update software packages on RHEL 8. We will also be working with a newer concept to RHEL 8, Application Streams. Application Streams allow multiple versions of user space components, providing more flexibility to customize RHEL 8 while maintaining system and application stability. In this lab, we will work with package module streams in RHEL 8.
