Native vs. Fedora 30


Posting this for future reference. If you are on Fedora 30 and attempting to use esy, you might get a message like this:

error unable to fetch @esy-ocaml/substs@0.0.1:         
  source: archive:
   error: error: run ['shasum' '--algorithm' '1'

That problem is that Fedora doesn’t automatically have shasum installed. Install it via:

sudo dnf install perl-Digest-SHA
