How To Fix Failed To Fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release on Ubuntu 12.04

FYI : Google Chrome has dropped 32bit Linux builds

$ apt-get update

Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.
This is because the 32-bit builds of Google Chrome have been discontinued

Quick Fix :

$ sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/etc/apt/sources.list.d/google-chrome.list"
$ sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/opt/google/chrome/cron/google-chrome"
$ sudo apt-get update
