Missing Epel 8 repository?

Sorry if I'm missing something basic, but I tried the role on Centos 8 and ran into the following.

Should we just remap to the fedora rawhide repository?

Copr repo for Mailman 3                                                                                                            1.5 kB/s | 341  B     00:00
