I am trying to install PiHole on a fresh Raspbian Stretch image and I keep getting the following error about non-root privileges.

pi@raspberrypi:~ $ sudo curl -sSL https://install.pi-hole.net | bash

  [✗] Root user check
      Script called with non-root privileges
      The Pi-hole requires elevated privileges to install and run
      Please check the installer for any concerns regarding this requirement
      Make sure to download this script from a trusted source

  [✓] Sudo utility check

And not surprisingly, PiHole does not work. Please advice.

Ok....I used the manual commands and it worked

wget -O basic-install.sh https://install.pi-hole.net
sudo bash basic-install.sh

The following worked better for me:
curl -sSL https://install.pi-hole.net | sudo bash
