What do you need to do these days to run an epel-8 mock build?
fedpkg mockbuild fails for me with
Error: Error downloading packages:
Status code: 403 for
https://infrastructure.fedoraproject.org/repo/rhel/rhel8/koji/latest/x86_...
(IP: 38.145.60.16)
I configured a RHEL subscription key so that I can make a rhel-8 root
successfully.
