First run update packages and upgrade Ubuntu Server

sudo apt update && sudo apt upgrade -y

To check if curl is installed and functioning on Ubuntu Server 24.04, run the command

curl --version

If curl is not installed, run this command to install it:

sudo apt install curl -y

Next, Disable the default systemd-resolved DNS stub listener to free up Port 53 for Pi-hole. Then, restart systemd-resolved with the following commands:

sudo sed -i 's/#DNSStubListener=yes/DNSStubListener=no/' /etc/systemd/resolved.conf

sudo systemctl restart systemd-resolved

Next intall Pi-Hole for standard bare metal server environments (not containerized) using the Official Automated Script – Run the official network installer command:

curl -sSL https://install.pi-hole.net | bash

OPTION: When installing on Ubuntu version 26.04, you will instead need to disable the Operating System version check when running the official network installer of Pi-Hole:

curl -sSL https://install.pi-hole.net | sudo PIHOLE_SKIP_OS_CHECK=true bash
