How do I install Arduino 1.5.7 on to Ubuntu 14.4

Using Arduino Installation & Troubleshooting
#1

How do I install an older version of Arduino 1.5.7 to Ubuntu 14.4 (latest version)?
I have already downloaded the Arduino 1.5.7 tgz 64bit file for linux and I have installed and run this command:

sudo apt-get update && sudo apt-get install arduino arduino-core
The core installed just fine.

what additional steps do I need to do to use Arduino 1.5.7?

You don't need to use apt-get when installing versions of the IDE downloaded from arduino.cc
Just unpack them and double click con IDE_FOLDER/arduino
