Install error: cp: cannot overwrite directory with non-directory

[hgezim]

Describe the bug

I'm having trouble installing nix on Mac OS 10.15.7 (19H2026).

Steps To Reproduce

I somehow ended up with a bad install which I tried to rectify by installing nix package manager again.

1. curl -L https://nixos.org/nix/install > ~/tmp/nix.sh
2. sh ~/tmp/nix.sh
3. Answer yes to all the prompt
4. Had to replace /etc/bashrc and /etc/zshrc with their version before nix changed them.

Expected behavior

A clean install of nix.

Actual behaviour

~~> Installing Nix

Jeeze, something went wrong. If you can take all the output and open

You'll have to follow the uninstall instructions before reinstalling it: https://nixos.org/manual/nix/stable/installation/installing-binary.html#macos

[hgezim]

I did.

The instructions tell you to remove the volume the files it fails to overwrite are on.

Ah, could be! I thought only successful installs need cleaning up. Figured it would clean up previous steps on failure.
