How To Install

New Method:

If you have Alta Web Components v2.56 or later then you can apply the .deb through the "Update" page on the website.

Old Method:

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>`
