Question
How do I enable or disable a repository?
Answer
You can either use yum-config-manager or edit the repository files manually to enable or disable a repository. It's recommended to use yum-config-manager.
To enable a repository with yum-config-manager:
yum-config-manager --enable repository
To disable a repository with yum-config-manager:
yum-config-manager --disable repository
The repository configuration files reside in the /etc/yum.repos.d/ directory.
Example:
/etc/yum.repos.d/example.repo
To enable a repository manually set "enabled=1" in the respective repository file.
To disable a repository manually set "enabled=0" in the respective repository file.
