Error fetching nixpkgs-unstable from my flake

Help

Hi, today when I went to update the inputs for my configurations flake I got this error.

[kat@desktop ~/.nixos] sudo nix flake update
error:
       … while updating the lock file of flake 'path:/home/kat/.nixos?lastModified=1729476398&narHash=sha256-BbkA6hLp%2BfNYvuofmBPN%2BvMvoyKnv3XN2t1ZzAa7qpM%3D'

       … while updating the flake input 'nixpkgs-unstable'

       … while fetching the input 'github:nixos/nixpkgs/nixos-unstable'

       error: tarball 'https://github.com/nixos/nixpkgs/archive/4c2fcb090b1f3e5b47eaa7bd33913b574a11e0a0.tar.gz' contains an unexpected number of top-level files

I do not recall changing any part of my configuration since the last time I updated the inputs and rebuilt. Does anyone else have this issue?

Here is my flake.nix:

{
    description = "Flakes are to Nix what automatic slicers are to bread.";

    outputs =
        inputs@{ ... }:
        let
            hosts = import ./hosts/hosts.nix;
            createHost =
                hostName: hostOptions:
                inputs."nixpkgs-${hostOptions.channel}".lib.nixosSystem {
                    modules = [ hostOptions.module ];
                    specialArgs = {
                        inherit inputs hostOptions;
                    };
                };
        in
        {
            nixosConfigurations = builtins.mapAttrs (
                hostName: hostOptions: createHost hostName hostOptions
            ) hosts;
        };

    inputs = {
        nixpkgs-stable.url = "github:nixos/nixpkgs/nixos-24.05";
        nixpkgs-unstable.url = "github:nixos/nixpkgs/nixos-unstable";

        home-manager-stable = {
            url = "github:nix-community/home-manager/release-24.05";
            inputs.nixpkgs.follows = "nixpkgs-stable";
        };
        home-manager-unstable = {
            url = "github:nix-community/home-manager/master";
            inputs.nixpkgs.follows = "nixpkgs-unstable";
        };

        nixvim-stable = {
            url = "github:nix-community/nixvim/nixos-24.05";
            inputs.nixpkgs.follows = "nixpkgs-stable";
        };
        nixvim-unstable = {
            url = "github:nix-community/nixvim/main";
            inputs.nixpkgs.follows = "nixpkgs-unstable";
        };

        stylix-stable = {
            url = "github:danth/stylix/release-24.05";
            inputs.nixpkgs.follows = "nixpkgs-stable";
        };
        stylix-unstable = {
            url = "github:danth/stylix/master";
            inputs.nixpkgs.follows = "nixpkgs-unstable";
        };

        firefox-addons.url = "gitlab:rycee/nur-expressions?dir=pkgs/firefox-addons";
        catppuccin.url = "github:catppuccin/nix";
    };
}

Turns out i’m dumb. A simple nix-collect-garbage fixed it.
