I currently have Git 1.7.1.0 installed but need to upgrade to 1.7.1.1 (at least). I tried running:
sudo apt-get update
sudo apt-get upgrade
and also tried
sudo apt-get install git-core
but each time I get a message indicating that there is no later version of git available. I have the following software sources configured in /etc/apt/sources.list
