Ubuntu is a Debian base Linux distribution with backing from Mark Shuttleworth via Canonical Ltd.

Upgrade to the last version:

    sudo apt-get install update-manager-core
    sudo do-release-upgrade

General system updates are handled with:

    sudo apt-get update
    sudo apt-get upgrade

But if when doing the updates you ever received a message stating "The following packages have been kept back" you'll need to issue the following (thanks to http://www.debian-administration.org/articles/69):

    sudo apt-get dist-upgrade

Mirrors:

If you're on Telstra then edit /etc/apt/sources.list with http://mirror.aarnet.edu.au/ubuntu/dists/ with the result that anything from there won't count against your cap.
