From there, it looks like the script does little more than add the `rpmfusion-free-release`, `rpmfusion-nonfree-release` and `folkswithhats-release` repositories. Of course since we started the install process through a shady insecure means, we should add the repos the same way. So every repo gets added via `dnf -y --nogpgcheck install https://url-to-repo-release-package`.
I went to browse the `folkswithhats` repo, but found it's hosted on AWS S3 and doesn't provide a directory index.
