Hi,
I’m new to NixOS and have been slowly getting into it and building up a configuration.nix over the last few days. After adding a few programs to install today I’m suddenly getting this strange error when doing a sudo nixos-rebuild switch.
error:
… while evaluating the attribute 'config'
at /nix/var/nix/profiles/per-user/root/channels/nixos/lib/modules.nix:1:12284:
… while calling the 'seq' builtin

I looked at some example configs online, and plenty of them start with the same line with the comman in exactly that place. I feel like I’m missing something obvious but I just can’t figure it out.
Here is my full /etc/nixos/configuration.nix
