Update from Ubuntu 12.0.4 to 14.04 (Python 2.7.6)

New Python for great good!

How to update your VM:

sudo apt-get update
sudo apt-get install update-manager-core
sudo do-release-upgrade -d
sudo reboot

By default, Ubuntu LTS release won't offer to upgrade to the next LTS until the first point release has been made. So `do-release-upgrade` won't show anything until Ubuntu 14.04.1 is released, which is scheduled for July 24th. Hence the `-d` flag.


You can also just erase your existing VM and start over by running `vagrant destroy`.
