If I execute the command "yum update" I obtain this message error: ----------- Setting up Update Process Setting up repositories Cannot find a valid baseurl for repo: update Error: Cannot find a valid baseurl for repo: update ----------- If I execute up2date command the error message is : ----------- There was a fatal error communicating with the server.
