Hi, I am trying to upgrade a nixos machine on GCE created from the old tempalted 14.12. I am unable to do so. I receive following error:
[root@localhost:~]# nixos-rebuild switch building Nix... error: syntax error, unexpected $undefined, expecting '"', at "/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/lib/sources.nix":52:49 (use ‘--show-trace’ to show detailed location information) error: syntax error, unexpected $undefined, expecting '"', at "/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/lib/sources.nix":52:49 (use ‘--show-trace’ to show detailed location information) error: evaluation aborted with the following error message: ‘This version of Nixpkgs requires Nix >= 1.10, please upgrade!

Thanks, Rohit
