While Chromium team ppas won’t release new versions of Chromium browser, Alex Shkop will try to maintain more-or-less fresh releases of Chromium. Two PPAs were built for Chromium stable and Chromium development version.

Install Latest Version of Chromium:

For now, two PPAs only provide packages for Ubuntu 12.04. Launch a terminal from the dash home or press Ctrl+Alt+T. Copy and paste following commands in terminal and hit enter to add the PPA:

To add Chromium Stable PPA (currently it’s version 21):

sudo add-apt-repository ppa:a-v-shkop/chromium

To add Chromium Dev PPA (currently it’s version 23):

sudo add-apt-repository ppa:a-v-shkop/chromium-dev

After added a PPA, update your repository and install Chromium:

sudo apt-get update && sudo apt-get install chromium-browser
