Hi
I’m trying to install Nix on my Clevo laptop (chinese hardware well supported by Linux) but when I start the nix install script I get that error:
[nixos@nixos:~]$ sudo nixos-install --show-trace
building the configuration in /mnt/etc/nixos/configuration.nix...
error: while evaluating the attribute 'config.system.build.toplevel' at /nix/var/nix/profiles/per-user/root/channels/nixos/nixos

Pretty lost here about exact source of problem as it doesn’t look linked with my config file
