Add Tailscale's package signing key and repository:

curl -fsSL https://pkgs.tailscale.com/stable/ubuntu/noble.noarmor.gpg | sudo tee /usr/share/keyrings/tailscale-archive-keyring.gpg >/dev/null

curl -fsSL https://pkgs.tailscale.com/stable/ubuntu/noble.tailscale-keyring.list | sudo tee /etc/apt/sources.list.d/tailscale.list

Install Tailscale:

sudo apt-get update
sudo apt-get install tailscale

Connect your machine to your Tailscale network and authenticate in your browser:

sudo tailscale up

You're connected! You can find your Tailscale IPv4 address by running:

tailscale ip -4

  If the device you added is a server or remotely-accessed device, you may want to consider disabling key expiry to prevent the need to periodically re-authenticate.
