Installing Pubstack on Ubuntu 14.04

These instructions are broadly based on https://github.com/NBCUOTS/pubstack/blob/master/README.md

1. Install Vagrant

2. Install Virtualbox either from Ubuntu repos or from Virtualbox website

3. Install latest ansible from ansible's PPA (and not from Ubuntu repos)

4. Install NFS daemon

sudo apt-get install nfs-kernel-server nfs-common rpcbind

Follow the remaining steps on README.md

Note: If you update the Linux kernel, chances are it will overwrite VirtualBox's kernel modules. So, you need to recompile some of the VirtualBox kernel modules. You can do this by:

sudo /etc/init.d/vboxdrv setup
