On ubuntu 14.04, if you try to install google chrome from the google.com, you may encounter some dependency error. libappindicator1 and libindicator7.
To solve the problem, you need to install these 2 software at the same time. i.e.
sudo apt-get install libappindicator1 libindictor7
That's it.
Hope it will be of help to all of you.
