I'm trying to upgrade to the latest version of ubuntu, it isn't working and I'm also not seeing any error messages... so I'm not really sure what the issue is or where to start looking... Any help would be appreciated.

There two separate issues here:

How to update Ubuntu, and how to upgrade Ubuntu.

Note: You should also NOT attempt to upgrade, unless you are already up-to-date (have completed update).

How to update (from command line):

Step 1: Update indices (to find what could be updated), then action those updates.

sudo apt-get update && sudo apt-get upgrade

Step 2: Action any further updates, for new / improved features. 

sudo apt-get dist-upgrade

Note: Your running the second part of 'Step 1' would not do very much on its own.

How to upgrade (from command line):

See link, as provided by fkraiem OR

sudo do-release-upgrade

Then, follow the on-screen instructions.

apt-get upgrade does not upgrade you to a newer version of Ubuntu, it only upgrades your packages to newer versions which were released for your current version of Ubuntu. Instructions to upgrade form 12.04 to 14.04 can be found here.

If you want to upgrade to the latest version of ubuntu you need to use sudo do-release-upgrade as sudo apt-get upgrade only updates all packages already installed on your system to the latest version.
