Summary I am using the nix flake as an input to build a nixos system. When I run nix flake update, I get an error about a non-existent input to cardano-node:

➜ nix flake update             
warning: Git tree '/home/solomon/Development/Nix/nixos-config' is dirty
error: input 'cardano-node/membench/cardano-node-snapshot/membench/cardano-node-snapshot/nixpkgs' follows a non-existent input 'haskellNix/nixpkgs-2105'
(use '--show-trace' to show detailed location information)

Steps to reproduce Steps to reproduce the behavior:

1. Add the cardano-node flake as an input:

   cardano-node = {
     url = github:input-output-hk/cardano-node;
   };

2. Add the cardano-node module to your nixosSystem modules:

       myMachine = nixpkgs.lib.nixosSystem {
         inherit pkgs system;
         modules = [
           ./config/machines/sower
           nixpkgs.nixosModules.notDetected
           home-manager.nixosModules.home-manager
           cardano-node.nixosModules.cardano-node
         ];
         specialArgs = {
           inherit inputs;
         };
       };

3. Run nix flake update

Expected behavior I would expect my flake lock to update successfully.

System info (please complete the following information):

• OS Name: Nixos
• OS Version 21.11
• Node version (output of cardano-node --version)
• CLI version (output of cardano-cli --version)

If the git revision is reported to be 0000000000000000000000000000000000000000, please use cabal build instead of cabal install to build the binaries because cabal install does not record the git revision in the binaries.

Screenshots and attachments

• If applicable, add screenshots, config files and/or logs to help explain the problem.

Additional context Add any other context about the problem here.

Update your version of Nix. This isn't an issue with cardano-node.

I'm on nixpkgs-21.11 using nix 2.5. Are you saying that cardano-node requires running nixpkgs-unstable?
