 mcwitt | regardless of hardware issues, if you're just starting out I don't think you should need to build anything from source.
The reason you're seeing this is the flake template you linked is pinned to an old revision of nixpkgs-unstable, and the build artifacts have likely expired from cache.nixos.org. I'll often update the nixpkgs pin as a first step when starting with a new template for this reason | 23:57:02 |
