How To edit repositories for your OM Lx system

There is another quick way to do this from command line (Using x86_64 Rock system as an example):

To enable main repository (should be already enabled by default):

$ sudo dnf config-manager --enable rock-x86_64 rock-updates-x86_64

To enable unsupported repository:

$ sudo dnf config-manager --enable rock-x86_64-unsupported rock-updates-x86_64-unsupported

To enable restricted repository (some packages in this repository may be illegal in some countries so be careful):

$ sudo dnf config-manager --enable rock-x86_64-restricted rock-updates-x86_64-restricted

To enable non-free repository (closed source code so we can’t fix anything inside these packages):

$ sudo dnf config-manager --enable rock-x86_64-non-free rock-updates-x86_64-non-free

If you wish to disable any repo substitute the option --disable for --enable. With the above example you should be able to extrapolate the commands to enable or disable anything you wish for any version. (Hint if you wish substitute either release, rolling, or cooker for rock.) (For different arch substitute znver1 for x86_64.)

And this is extremely, ultra, majorly, important. Do not mix the repository versions. If you pick Rock use Rock only. Same for Release, Rolling, and Cooker.
