This package contains the web controller components on an Alta-TS or Alta-2110 virtual machine. The same update file is applicable for both product configurations.
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>`
