dapptools only works on nix 2.5.1

[pyk]

When I tried to install dapptools on my fresh ubuntu, I discovered that dapptools only works perfectly with nix 2.5.1.

These are the problems that I encounter when using nix 2.6.x and 2.7.x

       at /nix/store/cz726jh79y4vciyvxx1q5kg3mi84zliw-env-manifest.nix:1:2732:

So instead of installing the latest version of nix, I use nix 2.5.1:

sh <(curl -L https://releases.nixos.org/nix/nix-2.5.1/install) --no-daemon
curl https://dapp.tools/install | sh

Looks like this is an issue with nix itself rather than dapptools? I think it should fix itself once NixOS/nix#6296 is backported to 2.7.

Am I missing something?

@d-xo yes I believe so
