How to Uninstall Nix

instructions.txt

Uninstalling nix:
1. Delete the systemd service and socket units

  sudo systemctl stop nix-daemon.socket
  sudo systemctl stop nix-daemon.service
  sudo systemctl disable nix-daemon.socket
  sudo systemctl disable nix-daemon.service
  sudo systemctl daemon-reload
2. Restore /etc/profile.d/nix.sh.backup-before-nix back to /etc/profile.d/nix.sh

  sudo mv /etc/profile.d/nix.sh.backup-before-nix /etc/profile.d/nix.sh

(after this one, you may need to re-open any terminals that were
opened while it existed.)

3. Delete the files Nix added to your system:

  sudo rm -rf /etc/nix /nix /root/.nix-profile /root/.nix-defexpr /root/.nix-channels /home/user/.nix-profile /home/user/.nix-defexpr /home/user/.nix-channels

and that is it.
