Manual installation for Linux Raspbian Jessie in Raspberry PI Variant Boards

Manual installation can be carried after installing the operating system and establishing Internet connection.

Pre-installation

Basic Instruction: Upgrade Operating System

Update the software repository for the operating system and upgrade all installed packages into their latest version.
