Ubuntu is an open source Linux operating system with an extensive feature set that has been successfully installed on all of the Vault platforms. The Ubuntu home page is at There are Long Term Support (LTS) versions and  current development versions. Multiple versions have been installed on the Vault. This article will describe installation of one of the recent desktop LTS versions.

To install a fresh instance of Ubuntu onto the Vault, there is a relatively straight forward process that is very similar to installing any operating system onto any computer.

  1. Obtain the installation image
  2. Download software to transfer the installation image to a USB drive
  3. Install the new image

There are a few steps along the way that I’ll highlight so as to make sure that the process is very clear

Note: If using the Vault FW1x, FW2x, or FW4x, be sure to use a USB stick and the USB keyboard with a plug that is relatively skinny.  The 2 USB ports on the Vault are very close to each other and if either the USB stick or the USB keyboard plug is too wide, you will not be able to plug both in at the same time, which will prevent you from doing the installation.

Obtain the Installation Image

Select “Download” from the Ubuntu main page.

Select Desktop from the Download page

Verify system requirements and select LTS Download

Your download should begin immediately and when it is completed you should have an image file (an example file name is: ubuntu-16.04.3-desktop-amd64.iso) downloaded that is ~1.6GB in size.

Download software to transfer the installation image to a USB drive

There are multiple applications to transfer the installation image to a USB drive. Protectli recommends “Rufus” for Windows and “Etcher” for the Mac. See this link for  detailed instructions on how to create a bootable USB drive using Rufus or Etcher.
