Can't upgrade nix.package to nix20 about nix-darwin HOT 3 CLOSED

The nix 1.11 daemon is not forward compatible with the 2.0 client. Most things work but IFD is one example that doesn't, the nixPath sanity checks fail because of that. I don't think there's a nice way to handle that automatically since the check is correct and should run with the target nix version.

Add this to your configuration temporarily to disable the checks until the daemon is upgraded.

{ config, lib, pkgs, ... }:
with lib;
{
  system.activationScripts.checks.text = mkForce "";
}

That warning is normal and will disappear when the system is upgraded, you can just ignore it.

Thank you for the suggestion! Removing the check worked and the upgrade went fine. Since I know I want to upgrade to 2.0 for all my machines, I borrowed the isNix20 logic check and made this conditional, worked like a charm.

Don't keep it in your config tho, the checks work once the daemon is running >=2.0
