RPM Support

I am trying to install pulp3 with rpm_plugin on Centos 7 using the ansible installer and am unable to get a working install. The first issue I hit was the libcomps error referenced here https://pulp.plan.io/issues/5853 and here https://github.com/pulp/pulp_rpm_prerequisites/pull/19/files

I eventually managed to get past that by manually adding the copr repo from mikedep333.

Now it seems I have hit another error and am at a complete loss. Can someone advise how to install the rpm plugin successfully?

I have tested installing without the plugin and this was successful though we need to be able to host rpms.
