Install git > 1.6.6 for Ubuntu Karmic Koala (9.10)

When building Chromium OS, you will need to use git to check out source. Unfortunately the git-core is way too old for check out.

Here is the way you can install git-core 1.7.0 from PPA

sudo add-apt-repository ppa:pdoes
sudo aptitude update
sudo aptitude install git-core subversion
