I'm using NixOS 23.11.6759.0638fe2715d9 (Tapir). I'm behind a proxy, but curl'ing the source manually works fine, so might be a bug in fetchzip.
Other than shown in the guide, a wrong SHA256 will cause
fetchzip
to fail with a cryptic curl errordefault.nix
hello.nix
result:
It works fine when using
fetchTarball
instead offetchzip
