Hi there. I mean the files that Academey instructors download from the academy ftp site. I'm aware that once the classroom is built you can run 'rht-verify --manifest' But that seems to show corrupted files in the rhel8 classroom when actually the files work fine.
so perhaps an individual check on each lab file, a bit like a "signature" that would ensure the integrity of the file. If the rht-verify command fails however, it usually indicates that the file did not properly upload - even if this does not necessarily mean that the file is corrupted :)
