Hello! I do have package in overlay which is coming from private git with expression similar to
world-src = nixpkgs.fetchgitPrivate {
url = "git@github.com:hello/world.git";
rev = "ea4e415ddc68a15341ae48b8252c2a27ec67b4cd";
sha256 = "0lxvl0y1p0haqw3jah0dn6i0lx3rbwd7bwyxirahi5xd44l2w4pm";
deepClone = true;
};
And sometimes nix is showing error similar to this without any particular reason
hash mismatch in fixed-output derivation '/nix/store/rc7065v6par2iwcy12drxl6nmy3kygsf-hello-ea4e415':
wanted: sha256:0lxvl0y1p0haqw3jah0dn6i0lx3rbwd7bwyxirahi5xd44l2w4pm
got: sha256:1zcxd6vxn5libks8x2rfda29mx2ii850wb2r31x77hq7g7jrs8yk
And often if I do give desired hash to the package like this
world-src = nixpkgs.fetchgitPrivate {
url = "git@github.com:hello/world.git";
rev = "ea4e415ddc68a15341ae48b8252c2a27ec67b4cd";
sha256 = "1zcxd6vxn5libks8x2rfda29mx2ii850wb2r31x77hq7g7jrs8yk";
deepClone = true;
};
Suddenly nix will want original hash back with opposite error
hash mismatch in fixed-output derivation '/nix/store/rc7065v6par2iwcy12drxl6nmy3kygsf-hello-ea4e415':
wanted: sha256:1zcxd6vxn5libks8x2rfda29mx2ii850wb2r31x77hq7g7jrs8yk
got: sha256:0lxvl0y1p0haqw3jah0dn6i0lx3rbwd7bwyxirahi5xd44l2w4pm
And then I give original hash, and it works. It’s very annoying. What is causing this errors and how to fix that permanently, without need of swapping hashes?
