$ sudo apt-get install google-chrome-stable

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

 google-chrome-stable : Depends: gconf-service but it is not installable

Note:

• This is neither my system, nor do I want to do a full system upgrade.

• Any modern browser will do.

• Flash plugin is also needed, if not included in the browser.
