error: function 'mkPackageOption' called with unexpected argument 'nullable'

Doesn't seem like a coincidence as nullable is a recently added parameter. It appears that NixOS gets evaluated with an old lib. What's in your NIX_PATH, and what's in your network's nixpkgs attribute?

[n8henrie]

Arch Linux, no channels configured, (flake based).

All inputs (including nixpkgs below) are tied to release-23.05 -- is that considered an old lib?

Pretty simple config:

  nixopsConfigurations.default = {
          inherit nixpkgs;
          network.storage.legacy = {};
          n8remote = {
            imports = [self.nixosModules.n8remote];
            deployment = {
              targetHost = "my.domain.com";
              targetPort = 42;
            };
          };
        };

$ env | grep NIX_PATH
$
$ nix-channel --list
$ sudo -i nix-channel --list
$ nix run nixpkgs#nix-info -- -m
 - system: `"x86_64-linux"`
 - host os: `Linux 6.1.32-1-lts, Arch Linux, noversion, rolling`
 - multi-user?: `no`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.15.0`
 - channels(root): `""`
 - channels(n8henrie): `"nixpkgs-22.11"`
 - nixpkgs: `not found`

EDIT: Ah, there it is (maybe): channels(n8henrie): "nixpkgs-22.11"

Wonder where that is coming from. I'll investigate.

Found an old nixopsUnstable pinned in nix profile (which I'm still not very used to using since my other machines are on NixOS), once unpinned and running nixops from unstable it worked. Thanks for pointing me in the right direction.

Evaluation succeeds. Now I'm back to being stuck at copying closure (#1557)
