Flatpak Repositories and Applications
RHEL 10 removed the whole container domain from EX200 and added two Flatpak objectives in its place, so there is very little RHCSA material on this yet. Configuring access to a repository and installing from it are both done here on a real remote, and both of the errors a first attempt produces are captured.

Written against the versions above. The `rhel` remote is pre-configured on every RHEL 10 install and points at `oci+https://flatpaks.redhat.io/rhel/`, which needs subscription entitlement - it cannot even be listed without it. This guide adds Flathub instead. **The commands are identical whichever remote you use**, which is what the objective is about.
