The problem seems to be that "pkg.racket-lang.org" has recoreded a checksum of "" for your package.
We'll have to investigate more how things got into a bad state (and change `raco pkg install` to deal with it in a better way), but if you go to "Manage Your Packages" at "pkg.racket-lang.org" and click "Update checksums", does it fix the checksum?
