To install the Endless Lifecycle Support repository on a server, download an installation script and run it with a license key. The installation script registers the server in the CLN using the license key, adds a PGP key to the server, and creates the ELS repository.

   wget https://repo.els.tuxcare.com/centos8.4-els/install-centos8.4-els-repo.sh
