Remove install-no-user for F27 live till I can make it work
    
    This doesn't really work, it needs a product with that explicit
    version to make it work, apparently. I think I'd better just
    take this out and read up again on how the wildcards work rather
    than just messing around with it. I'll put it back if I can be
    reasonably sure of making it work.
