Answer 1

It means webdriver is unable to find google chrome. Do you have the browser installed?

For minimal ubuntu development you only need this package:

sudo apt-get install chromium-chromedriver

Or later versions can be downloaded (set-up tips)

Answer 2

Basically what the error says is that the webdriver is unable to find google chrome. Make sure you have installed it in the correct place on your machine.

This issue goes into more detail about it, with the exception of being ruby over python:
