Setting up Tailscale on Ubuntu 21.04 (hirsute)

Packages are available for x86 and ARM CPUs, in both 32-bit and 64-bit variants.

  1. Add Tailscale’s package signing key and repository:

    curl -fsSL https://pkgs.tailscale.com/stable/ubuntu/hirsute.noarmor.gpg | sudo tee /usr/share/keyrings/tailscale-archive-keyring.gpg >/dev/null
curl -fsSL https://pkgs.tailscale.com/stable/ubuntu/hirsute.tailscale-keyring.list | sudo tee /etc/apt/sources.list.d/tailscale.list

  2. Install Tailscale:

    sudo apt-get update
sudo apt-get install tailscale

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

    sudo tailscale up

  4. 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.
