inputplumber doesn't build with latest nixos-unstable -- nix-prefetch-git not found #545
Description
With the latest nixos-unstable, and the latest jovian flake (today's), I get the following error when rebuilding:
error: Cannot build '/nix/store/1s28jl436ridljlvq4y357jy2k63wa4h-cargo-deps-vendor-staging.drv'.
Reason: builder failed with exit code 1.

I worked around it for now by using the nixpkgs version of inputplumber with mkForce.
I'm nowhere near an expert with nix, so it's always possible it's my fault, but it built with the previous version of nixpkgs-unstable without issue.
