If you are running a 64 Bit system, then use this:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
then:
sudo dpkg -i ./google-chrome*.deb
and to finish:
sudo apt-get install -f
This is the same as jrg's reply, but you change the i386.deb to amd64.deb.
EDIT: The past couple of times I have not had to do the install -f. It seems to have all needed after installing.
Good Luck!!
