Setup of yum ULN Mirroring
Have an OEL 8 server that is registered with ULN and it is subscribed to channels for OEL6, 7, 8 and 9. The goal was to have a single server act as a repo for the various OEL6,7,8,9 clients in the environment.
Once the server was subscribed to the different OS version channels, yum update doesn't work on the central repo server because it tries to pull packages for other OEL versions plus more errors.
