Took me a bit longer than expected but I’ve corrected the koji tags and pushed the packages. I now see the missing packages you mentioned. My install is still running so I can’t confirm it’s really fixed.
You can work around it by installing foreman-release and then disabling GPG checking in /etc/yum.repos.d/foreman-plugins.repo. I think that should at least allow you to install and test. Will update here ofc when it’s fixed.
