A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available i         


        

Answer 1

You need to install either the openjdk-7-jre or oracle-java7-jre package.

sudo apt-get install openjdk-7-jre

Note that openjdk-7-jre is easier to install, because it's available via the standard Ubuntu repository, whereas you have to build oracle-java7-jre yourself using java-package.
