status of nix build? (or how to use Daedalus on NixOS?)

[colemickens]

I thought using the nix flake would be a good way to get Daedalus running on a NixOS system.

However:

• the nixpkgs is quite, quite old
• nothing seems to be cached in the provided cache

I'm not overriding any inputs, so the lack of cache hit was quite surprising.

Is this... a good way to use Daedauls on NixOS? Is there a better option?

Thanks!

It's a more than a bit frightening to think I'm using such old nixpkgs for a crypto wallet...

Wow GitHub really has issues with spam huh.

Hey @colemickens, this flake.nix fragment:

daedalus/flake.nix

Lines 57 to 61 in f02475f

	nixConfig = {
	extra-substituters = ["https://cache.iog.io"];
	extra-trusted-public-keys = ["hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ="];
	allow-import-from-derivation = "true";
	};

… will not be used, unless you're in trusted-users and allow it explicitly. But that is a security hole (giving your user root privileges), so I would recommend to just add IOG cache to your global system configuration. Remember to restart the Nix daemon, but that's more for macOS users, as it happens automatically on Linux.

As for the old Nixpkgs, they're used mostly for building, the actual runtime dependencies (including Electron version) are specified in package.json and, more specifically, yarn.lock. Both cardano-wallet and cardano-node have their own Nixpkgs pins, and we don’t override these. But it's a good catch, I will update them, perhaps pinning to what cardano-node uses. Thanks!

I did allow the cache and the trusted key. Ultimately I used another wallet to do the consolidation I needed to do. I likely won't be able to weight in much more. But I appreciate the reply and consideration. Cheers!
