How To Install

From website:

Navigate to the "Update" page on the website, upload the .deb file and then click "Apply".  You will be re-directed to the homepage after the update completes.

From command line:

Download the .deb file to your VM from a web browser (you can use the desktop or any other folder), or bring it over by USB or another file transfer mechanism after downloading to another computer. Make sure the extension remains ".deb", if it is different this may be an indication your computer has tried to unpack it automatically on downloading, which could render it unusable. 

Right-click on the file in the VM environment and select the "Install" option to upgrade (or, from a command shell, use `sudo dpkg -i <filename>`
