error: experimental Nix feature 'flakes' is disabled; add '--extra-experimental-features flakes' to enable it

Do you use flakes in your configuration? If so, can you show it to me?

[rick73erc]

I have followed the Quickstart guide step by step
However I can find the flake from step1
nix flake init --template github:nix-community/disko-templates#single-disk-ext4

Maybe you have flake.nix in /mnt/etc/nixos
Try to run sudo nixos-install --extra-experimental-features flakes

[rick73erc]

It just returns
sudo nixos-install --extra-experimental-features flakes
/run/current-system/sw/bin/nixos-install: unknown option `--extra-experimental-features'

I will again later off to bed now. Thanks for your help.

Check what's inside /mnt/etc/nixos later.
