It is very easy to install google drive on Windows OS, but not possible in UBUNTU. Here are few commands to make that task easier for UBUNTU Linux users. 

sudo add-apt-repository ppa:thefanclub/grive-tools
sudo apt-get update
sudo apt-get install grive-tools

Execute the above commands one by one in the terminal to make the installation success. If you want to see the video demonstration, watch this video.

 

This installation tested in UBUNTU 14.04.
