Check synchronization status and scheduling
A repository is a storage location for software packages (RPMs). RHEL uses dnf commands to search a repository, download, install, and update the RPMs. The RPMs contain all the dependencies needed to run an application.
The length of the initial synchronization of Red Hat content can vary. If you choose to synchronize repositories as soon as possible, you can synchronize all repositories in Red Hat Update Infrastructure 5 from the CLI. For the available commands — including pausing and resuming automatic synchronization — see Managing repository synchronization from the CLI.
