Interesting - just ran into this as well with - folkertdev/elm-deque
I downloaded the source code for folkertdev/elm-deque 3.0.1 from:
https://github.com/folkertdev/elm-deque/zipball/3.0.1/
But it looks like the hash of the archive has changed since publication:
Expected: d68f199182be5e93097a1e56869e5b29e7bbda91
Actual: e9b1de164452ad0e32ceda86fd5c8d46b9dcfaa4
