Chapter 10. 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.

Important

Define your repositories in the .repo file instead of /etc/dnf/dnf.conf.

The /etc/dnf/dnf.conf file contains the [main] section and can contain one or more repository sections ([<repository-ID>]) that you can use to set repository-specific options. The values you define in individual repository sections of the /etc/dnf/dnf.conf file override values set in the [main] section.

10.1. DNF repository options

The /etc/dnf/dnf.conf configuration file contains repository sections with a unique repository ID in brackets ([]). You can use such sections to define individual DNF repositories.

Important

Repository IDs in [] must be unique.

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

10.2. Adding a DNF repository

You can add a DNF repository to your system by using the dnf config-manager --add-repo command.

Procedure

  1. Add a repository to your system: 

    # dnf config-manager --add-repo <repository_URL>

    Note that repositories added by this command are enabled by default.

  2. Review and, optionally, update the repository settings that the previous command has created in the /etc/yum.repos.d/<repository_URL>.repo file: 

    # cat /etc/yum.repos.d/<repository_URL>.repo
Warning

Obtaining and installing software packages from unverified or untrusted sources other than Red Hat certificate-based Content Delivery Network (CDN) is a potential security risk, and can lead to security, stability, compatibility, and maintainability issues.

10.3. Enabling a DNF repository

You can enable a DNF repository added to your system by using the dnf config-manager command.

Procedure

  • Enable a repository: 

    # dnf config-manager --enable <repository_id>

10.4. Disabling a DNF repository

You can disable a DNF repository added to your system by using the dnf config-manager command.

Procedure

  • Disable a repository: 

    # dnf config-manager --disable <repository_id>
