If you do the suggestions in the error message, does that allow you to get further in the install process?

Yes I removed the entire entry from fstab using vifs

but when I tried to reinstall nix I got this;

Ah, I see. To get past this, you have two options:

1. Accept the existing GID and pass --nix-build-group-id 30000
2. Follow the upstream uninstallation instructions and retry the installation: https://nix.dev/manual/nix/latest/installation/uninstall.html#macos
