Virtualmin-Release Package 1.0-4.rhel Unsigned

Yum is requesting to update the following package:

virtualmin-release.noarch 0:1.0-4.rhel

However, it fails with the following error:

Package virtualmin-release-latest.noarch.rpm is not signed

Aside from the error, what is this update for?

Thanks,
Alan
