[BUG] Nixos installation via flakes + home-manager is broken

[Sipepper]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest available version of Noctalia.

Bug description

After sudo nix flake update the programs.noctalia-shell.enable = true stopped working, i.e. The option home-manager.users.mlys.programs.noctalia-shell does not exist.

Steps to reproduce

I have the following config structure:
Noctalia in the flake inputs

    noctalia = {
      url = "github:noctalia-dev/noctalia-shell";
      inputs.nixpkgs.follows = "nixpkgs";
    };

Separate noctalia.nix file

{ pkgs, inputs, ... }:
{
  imports = [
    inputs.noctalia.homeModules.default
  ];

  noctalia-shell.enable = true;
}

Imported into home.nix and

      nixosConfigurations = {
        desktop = nixpkgs.lib.nixosSystem {
          specialArgs = { inherit inputs; };
          modules = [
            ./configuration.nix
            ./hardware-desktop.nix
            {
              system.stateVersion = "24.05";
              boot.loader.grub.useOSProber = true;
            }
            determinate.nixosModules.default
            home-manager.nixosModules.default
            {
              home-manager.extraSpecialArgs = { inherit inputs; };
              home-manager.users."mlys" = {
                imports = [ ./home.nix ];
                programs.vscode.enable = true;
              };
            }
          ];
        };

Full config can be found at https://codeberg.org/mlys/mlys_flake

Expected behavior

NixOS rebuilds successfully.

Actual behavior

System can't rebuild itself.

I really doubt it's broken as we have many community members running nixOS on discord, probably a setup issue on your side. You may get better support on discord in our #nixOs channel.

Tagging @linusammon because why not!

Separate noctalia.nix file

It's programs.noctalia-shell not noctalia-shell

Sorry, there was a typo related to noctalia-shell.enable. Before creating the issue, I tried to reorganize my config. After nothing helped, I changed config back, but forgot to add programs before noctalia-shell. In other words, at least in my case the issue persists

programs.noctalia-shell is the v4 module but you have main / v5 as your input, v4 now lives in legacy-v4. Should all be in the docs of whatever version you wanna use.

Yep, found it on the main page. Sorry for not searching long enough. Thank you for the help!
