Install Chrome in Ubuntu 12.10 x64

While installing 64-bit chrome deb under Ubuntu 12.10, error occurred:

"The package is of bad quality

E: google-chrome-stable: file-in-etc-not-marked-as-conffile etc/cron.daily/google-chrome"

Then I used dpkg until I got another error:

sudo dpkg -i deb_package_name.deb

Selecting previously unselected package google-chrome-stable.
(Reading database ... 269204 files and directories currently installed.)
Unpacking google-chrome-stable (from chrome.deb) ...
dpkg: dependency problems prevent configuration of google-chrome-stable:

  Package libgconf2-4 is not installed.
dpkg: error processing google-chrome-stable (--install):

Solution:
