Hello, I'm running into some issues with the linux-builder. It used to work before so I'm not sure what's changed to cause it to no longer work. At first I was getting SSL certificate errors, so I just updated, but now it's giving errors like this one:

$ nix build .\#checks.aarch64-darwin.metrics-vm -L                                                                                                      [15:49:53]

This is a qemu vm built for aarch64-linux on aarch64-darwin

Here's some other info about my system if it helps:

MacOS 13.5.2 (22G91)
nix (Nix) 2.31.2

Here's my configuration: github.com/eureka-cpu/nix-darwin

Here is a link to the configuration I am trying to build for, and the command I ran:
https://github.com/rainshowerLabs/blutgang/pull/97

nix build .#checks.aarch64-darwin.metrics-vm

I added these settings which seem to have helped so far:

{
  nix.linux-builder = {
    enable = true;
    ephemeral = true;
    maxJobs = 4;
    config = {
      virtualisation = {
        darwin-builder = {
          diskSize = 40 * 1024;
          memorySize = 8 * 1024;
        };
        cores = 6;
      };
    };
  };
}

I’m not sure, but I don’t think so. Clang had that as a warning since Clang 16, and now it is a hard error since Clang 20.
