Describe the issue
Incorrect link to checksum files for ppc64le and s390x on https://alt.fedoraproject.org/en/verify-prereleases.html Either the CHECKSUM files are not created at all or they are at different location. Eg. https://alt.fedoraproject.org/en/static/checksums/Fedora-Server-29_Beta-1.5-ppc64le-CHECKSUM returns a 404 page. Only aarch64 seems OK. It might be a websites problem.
