Currently, we only officially support Ubuntu 16.04, with limited support for 14.04. The following instructions should work on other versions of Ubuntu as well.

1. To start we need to add some third-party PPAs in order to get the correct versions of Java and Gradle needed to run our software.

   Code Block
   language bash
   sudo apt-add-repository ppa:cwchien/gradle sudo apt-get update

2. Install Java, make sure to install the OpenJDK. The Oracle JDK license does not allow controlling embedded systems. For Ubuntu 14.10 and newer:

   Code Block
   language bash
   sudo apt-get install openjdk-8-jdk openjfx

   For versions of Ubuntu older than 14.10, such as 14.04, OpenJDK 8 is not available in an official backport. Instead, execute

   Code Block
   language bash
   sudo add-apt-repository ppa:openjdk-r/ppa sudo apt-get update sudo apt-get install openjdk-8-jdk sudo update-alternatives --config java sudo update-alternatives --config javac

3. You can verify that your system is using the correct JDK by running

   Code Block
   java -version

   The output should look something like

   Code Block
   java version "1.8.0_91" Java(TM) SE Runtime Environment (build 1.8.0_91-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

4. Install Gradle

   Code Block
   language bash
   sudo apt-get install gradle

   Make sure you have a version >= 2.10 by running

   Code Block
   language bash
   gradle -v

5. Install Git

   Code Block
   language bash
   sudo apt-get install git
