  1. Connect the system to the IdM Server:

  1. Enable Red Hat’s CodeReady Linux Builder/AlmaLinux PowerTools/CRB Repository:

For Red Hat Enterprise Linux 8

subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
dnf distro-sync

For AlmaLinux 8

dnf config-manager --set-enabled powertools
dnf distro-sync
