This is a result of your server’s inability to update and resolve the repositories. Verify the resolvers that are configured on the server. Look for the /etc/resolv.conf file. Verify that the resolvers can be connected and are accurate. Update the free resolvers if not. Here’s an example.

nameserver 8.8.8.8
nameserver 4.4.4.4
