Steps To Reproduce

Steps to reproduce the behavior:
nix develop on this flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
  };

  outputs = { nixpkgs, ... }:
    let
      python_package = "python3";
      pypkgs = ps: with ps; [
        dasbus
      ];
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
      py = pkgs.${python_package}.withPackages pypkgs;
    in
    {
      devShells.x86_64-linux.default = pkgs.mkShell {
        packages = [
          py
        ];
      };
    };
}

Metadata

Please run nix-shell -p nix-info --run "nix-info -m" and paste the result.

[user@system:~]$ nix-shell -p nix-info --run "nix-info -m"
 - system: `"x86_64-linux"`
 - host os: `Linux 6.6.33, NixOS, 24.11 (Vicuna), 24.11.20240709.feb2849`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.18.4`
 - nixpkgs: `/nix/store/5w7nhyvrgsa81h0kyifmbl6j97hvlzh5-source`

^^ But this is misleading because the nixpkgs version I am trying to build from is not that version since this happened after I updated my flake.lock so the new version hasn't been pinned yet for me

Any current bypass for this in the meantime? I've tried overriding to disable tests to no avail.
