The DNF Disable Repo Command In CentOS

There are moments when we prefer to stick with the older versions of the packages rather than install the newest ones. To prevent the packages from that repository from also being upgraded in such circumstances, we can exclude that repository. When software requires a specific version package in order to function properly, this will be useful.

The DNF disable repo command in CentOS can be used to disable a particular repository. A repository can be disabled so that DNF (Dandified YUM) cannot use it as a source for software packages. This can be helpful if we wish to temporarily or permanently block the setup or updates of packages from a specific repository.

To use the dnf disable repo command, follow these steps:

1. Viewing the list of accessible repositories and their current status is a good idea before disabling a repository. We can use the below code:

The result of this operation is a list of repositories with their status shown.

2. Also, we need to know the name of the repository we wish to disable in order to disable it. For instance, we can use the below code:

In order to disable a repository, replace it with the repository’s actual name. DNF will stop using the repository as a source for software packages after executing this command.

3. We can confirm that the repository has been successfully disabled by running the following command after executing the dnf config-manager --set-disabled:

The result should now show the repository that we disabled as disabled.

We can manage which software packages are accessible for installation and updates on the system by turning off a repository. When we wish to limit access to specific repositories in order to preserve system security and stability, it can be useful.
