In reply to @dazai:matrix.org

in the flake tutorial it has this

colmena = {
  meta = {
    nixpkgs = import nixpkgs {
      system = "x86_64-linux";
      overlays = [];
    };
  };

meaning i have to change my flake depending what machine i'm deploying on, does that make sense?

interestimg issue 🤔
I might have a similar one when I get my rpis...

Essentially you would need to figure out the architecture of the system colmena/nix is running on and use that in the import statement.
