Choose your method:
- Method one:
In AdminCP
Server Settings -> Yum Manager.
Check the names of the repositories. Every CentOS-** repo should have CWP at the beginning of its name.
- Method two:
ls -all /etc/yum.repos.d
Should give the same output as method 1
For some reason, my server has the original repos restored. Weird. Maybe I need to apply it every time dnf/yum itself gets updated.
