[msh@localhost ~]$

how to remove ozonos repo from my system.
I found this page:
https://docs.fedoraproject.org/en-US...ositories.html

It shows Adding, Enabling and Disabling but no Removing.

and how can I check what options or sub command under config-manage command.
I tried these:

Code:

# dnf config-manager help

Code:

# dnf help config-manager

Code:

# dnf config-manager --help

they are useless.

I expect to see like this:

Code:

--add-repo blur blur ...

--set-enabled blur blur ...

--set-disabled blur blur ...

dnf has a lot of advance commands and options but missing simple ones in common sense, I think.
