libjli.so "No such file or directory" while trying to run Arduno IDE

I downloaded Arduino IDE and extracted it. When trying to run it:

./arduino

It throws up an error:

/opt/arduino-1.6.9/java/bin/java: error while loading shared libraries: libjli.so: caot open shared object file: No such file or directory

I then tried:

sudo apt-get install openjdk-8-jre-headless

But still the same error. No change if I use sudo.
