error 404 installing google chrome
Solution 1:
This is because Google have stoped support for Chrome in 32-bit linux distros.
In a double-whammy, March will also see Google Chrome stop supporting Ubuntu 12.04 LTS (which will receive critical and security bug fixes from Canonical until mid 2017).From this March only 64-bit versions of Ubuntu 14.04 LTS (or later) will receive new versions of the browser from Google . Source
You should try Chromium or Opera of other browser Or
You should Install Ubuntu 64-bit.
