How to Safely Remove a DNF Repository
After a major upgrade of Fedora or CentOS, we can be left with an outdated third-party vendor repository. Now maybe we went ahead and added the newer version of that repository, but how do we safely remove the old one?
First, we need to identify the repo id that we wish to remove.
repo id repo name fedora Fedora 38 - x86_64 fedora-cisco-openh264 Fedora 38 openh264 (From Cisco) - x86_64 fedora-modular Fedora Modular 38 - x86_64 updates Fedora 38 - x86_64 - Updates updates-modular Fedora Modular 38 - x86_64 - Updates ancient-repo Fedora 1
We can remove all the packages from the repo id
ancient-repo with the following command:
dnf repository-packages ancient-repo remove
Use this opportunity to double check that what it’s going to remove is okay for your system. Some applications may not have newer versions in the other repositories, so you might have to hunt those down separately.
Also keep in mind, that this command will uninstall any unused dependencies from other repositories as well.
After removing the packages within the deprecated repository, we can remove it from the repo list.
ancient-repo with your repo id.
