Install latest ubuntu kernel

ubuntu-kernel-upgrade.sh

#!/bin/bash
# Author: Paul Rafferty <raffraffraff@gmail.com>
# Purpose: Finds, downloads and installs the latest upstream kernel for Ubuntu

# Note: If your host requires proprietary modules (eg: virtualbox, nvidia, fglrx, bcmwl etc) then
#       you require the extra modules package which is not available here. You can try to uninstall
#       these modules first before installing the upstream kernel. Otherwise, don't proceed - your
#       new kernel probably won't boot.
