I am trying out nix flakes for my /etc/nixos/configuration.nix, and now I’m unable to do nixos-rebuild switch without errors.
I get:
╭─hhefesto@Olimpo ~

FileNotFoundError: [Errno 2] No such file or directory: '/nix/var/nix/profiles/system-6-link/kernel'
warning: error(s) occurred while switching to the new configuration
From /nix/var/nix/profiles/system-1-link to /nix/var/nix/profiles/system-5-link the kernel file does exist. From /nix/var/nix/profiles/system-6-link to /nix/var/nix/profiles/system-20-link it’s not there (I guess system-6-link was my first configuration with flake).
This is my flake:

This is the second third day I’ve tried to fix this without any luck. Any guidance is greatly appreciated.
Thank you very much for reading,
Daniel
edit: removed comments and trimmed down some of configuration.nix . I’m unsure of how much more I can trim it down: suggestions very welcomed.
