How to Install 64bit Chromium / Google Chrome in Ubuntu

In case you don't know: Chromium is the open-source project behind Google Chrome so do not mix them.

Google Chrome 64bit for Ubuntu

Before downloading, remember that installing Google Chrome will result in also adding the Google repository.

Download Google Chrome 64bit Ubuntu .deb

Chromium

If you wish, you can install Chromium 64bit instead of Google Chrome:

* The amd64 package is no longer using ia32-libs. It contains *native* 64bit debs.

1. Add the Chromium PPA repository:

sudo sh -c "echo 'deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu jaunty main' >> /etc/apt/sources.list"

Or, if you don't use Jaunty, replace it with your current Ubuntu version.
2. Add the GPG key:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 4E5E17B5

3. Install Chromium:

sudo apt-get install chromium-browser

The same PPA also works for the 32bit version of Chromium!

To enable Flash support, you should follow the steps here: Chromium or Google Chrome (almost the same way).
