There are two ways to install Google Chrome: using the graphical interface (for example, Ubuntu Software Center) or using the command line (for example, apt-get).
To install Google Chrome using the graphical interface, open the Ubuntu Software Center and search for "google chrome". Once you find the Google Chrome package, click "Install" to install it.
To install Google Chrome using the command line, open a terminal and type:
