No, that's the reason it *succeeds*!
Guix is mostly content-addressed, meaning that the hash identifies
a file. If you don't change the hash, you're not asking for a new
file, by definition. URLs are like directions (hence: ‘locator’),
not identifiers.
You can easily generate a bogus-but-valid hash by negating the
first digit, which (in nix-base32 at least), can only be either 0
or 1. Guix will then print the correct hash of whatever it found
at the URI you specified.
OK to close as NOTABUG?
Kind regards,
T G-R
