install f.lux in Ubuntu

F.lux changes your computer display’s color temperature according to location and time of day. It was designed to reduce eye strain during night-time use and disruption of sleep patterns.

The f.lux for Linux is a command line daemon and the GUI is an indicator applet created by Kilian Valkhof. Though Kilian’s repository does not update anymore, you can still get the applet for Ubuntu 16.04, and Ubuntu 15.10 via below steps.
