Add the Meshtastic Debian Repository

Download the public key and put it in /etc/apt/keyrings/meshtastic-deb.gpg. You can achieve this with:

wget -qO- {{ site.url }}/meshtastic-deb.asc | sudo tee /etc/apt/keyrings/meshtastic-deb.asc >/dev/null

Next, create the source in /etc/apt/sources.list.d/

echo "deb [arch=all signed-by=/etc/apt/keyrings/meshtastic-deb.asc] {{ site.url }}/deb stable main" | sudo tee /etc/apt/sources.list.d/meshtastic-deb.list >/dev/null

If you want to have the latest version of the software, you can replace stable with unstable.

Then run sudo apt update && sudo apt install -y meshtasticd.
