9장. Managing custom software repositories

You can configure a repository in the /etc/dnf/dnf.conf file or in a .repo file in the /etc/yum.repos.d/ directory.

The /etc/dnf/dnf.conf file contains the [main] section and can contain one or more repository sections with a unique repository ID in brackets ([]), for example, ([<repository-ID>]). You can use these sections to define individual DNF repositories by setting repository-specific options. Note that repository IDs must be unique. The values you define in individual repository sections of the /etc/dnf/dnf.conf file override values set in the [main] section for this repository.

For a complete list of available repository ID options, see the [<repository_ID>] OPTIONS section of the dnf.conf(5) man page.

Consider adding your custom repositories in separate .repo files instead of the /etc/dnf/dnf.conf DNF configuration file to avoid possible issues if other programs modify the DNF configuration file.

You can add the DNF repository to your system by using the dnf config-manager --add-repo command. Repositories that you add with this command are enabled by default. However, you can also use the dnf config-manager command to disable the repository.
