If you have another browser installed, you can simply go to https://www.google.com/chrome/browser/features/html. Choose Debian/Ubuntu and download it.
Alternatively, I found these instructions at [this link][1].

Add key:

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

Set Repository:

sudo sh -c 'echo ''deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main'' >> /etc/apt/sources.list.d/google-chrome.list'

Install package:

sudo apt-get update

sudo apt-get install google-chrome-stable
