Yum repo checksum problem on installation

We’re getting an error while using the erlang yum repository:

$ sudo yum install erlang

etc.

I’ve tried yum --enablerepo=erlang clean metadata but the problem persists. Could someone verify the metadata file or otherwise advise what we can do to resolve this problem kindly?

Thank you for your consideration.
