To install the latest Chrome browser (development version, with minimal testing), go the this url:
Accept the EULA to download the .deb package (in this case for the i386, to download to 64 bit architecture or the beta version instead of the development version, go to the Chrome Release Channel to choose the right package).
After downlaoding, install the package
sudo dpkg -i google-chrome-unstable_current_i386.deb
This will install the most recent development version (today is the 27.0.1423.0-r184590). It asked me for libxss1, don’t know if it was removed when I remove Unity, or if it is a new requirement from Chrome, I simply installed it by running the following command before installing Chrome again:
sudo apt-get install libxss1
Now you have a bleeding edge Chrome! The development version is updated more or less weekly, and at least minimally tested.
