Nix installation issue

I’m trying to install Nix but getting an issue that it thinks I still have Nix installed. Asks me to run “sudo rm -rf /etc/nix /nix /root/.nix-profile /root/.nix-defexpr /root/.nix-channels /home/paul/.nix-profile /home/paul/.nix-defexpr /home/paul/.nix-channels” which I run and verify worked.

I re-run installer and it still gives me same error. I’ve tried running this and rebooting and still get this error.

Please help!

I found that some other program had nix installed. So I went to do a nix build and get an error “error: the build users group ‘nixbld’ has no members”.

I assume I have to add my account to the nixbld users group.

did you do multi or single user install?
