@Amir-Ahmad Oh I think you probably put this in
~/.config/nixpkgs/overlays/
directly, yes? I suppose I should have elaborated. Your directory structure should look likeThe nested folder name (
userPackages
above) doesn't matter, but the two files do need to be nested in a folder, and the main file isdefault.nix
in this folder.What this does is it makes
userPackages/default.nix
to be the actual overlay, and that in turn imports./packages.nix
to construct theuserPackages
set. By putting both files in the top level overlays folder you instead make them two separate overlays and thepackages.nix
file is then trying to overwrite each package with itself, which causes infinite recursion.
