Is there some reference on how to install the latest Arduino using only Terminal? I've found https://playground.arduino.cc/Linux/Ubuntu but it states that in this way only 1.0.5 is available.
I'm building a Vagrant image with a development environment for some specific cases and I'd like everything to be set up during image creation without the end having to install anything after the initial image setup. With this idea in mind I'm also looking for a way to install some additional boards via Boards Manager without user having to touch the IDE. Is this possible and could someone be so kind to point me to some resources to get started?
