Okular - Installation
We have found that the Okular document viewer works well for our needs.
Okular is free, works across most platforms, and preserves your annotations when you switch between devices or operating systems.
We have installed Okular on your virtual machine, but just in case here are the Linux installation instructions.
Note: GUI applications like Okular won't run as root. All okular commands must be executed by a regular user.
