If you know what application you want to install, you can verify that it's in the repository by searching for its name or even just part of its name: $ sudo dnf search toolbox Updating Subscription Management repositories. For instance, to enable the rhel-9-for-x86_64-supplementary-rpms repository: $ sudo dnf config-manager -enable rhel-9-for-x86_64-supplementary-rpms To enable a repository, use the dnf config-manager subcommand with the -enable option and the name of the repository as listed.

It's a long list, so pipe it through the more pager to scroll through it: $ sudo dnf repolist -all | moreĪmq-interconnect-textonly-1-for-middleware-rpms Red Hat A disabledĪmq-textonly-1-for-middleware-rpms Red Hat J disabledĪnsible-automation-platform-2.2-for-rhel-9. To see the repositories enabled on your system, use the dnf repolist command along with the -all option. These include the BaseOS, AppStream, Red Hat Linux Builder (previously called CodeReady Linux Builder), and Supplementary repositories. Search software repositoriesĪpplications available on Red Hat's servers are divided into several software repositories.

RHEL provides two ways to interact with its package manager: the dnf command and the GNOME Software app. Using a package manager ensures that every file installed on your system is dutifully recorded in a database, and each package can be updated when a new release is available. On Red Hat Enterprise Linux (RHEL), that central hub for application installation and maintenance is the dnf (formerly known as yum) package manager. The best way for that to happen is to install software from a central hub. However, when an application is mission-critical, it's important that you get timely and reliable updates.
