error: Could not find latest nixpkgs version

[Alexnortung]

I just wanted to try using snow, but when I try to install a package, I get an error:

$ nix run github:snowflakelinux/snow -- install lolcat
error: Could not find latest nixpkgs version

NixOS version: 22.11
Nix version: 2.11.1

Do you have a flake with nixpkgs as an input?

[Alexnortung]

I do have a flake with nixpkgs as an input. However I was using the command from my home folder. I think there needs some documentation on how to use snow.

It should work ootb how you ran it. What does your nix registry list look like? Or anything on your network configuration that would stop you from accessing this: https://raw.githubusercontent.com/snowflakelinux/nix-data-db/main/nixpkgs-unstable/nixpkgs.ver?

This is the output of nix registry list for my system.
