I am using Ubuntu 16.04 and it does not have the latest version of poppler.
This is blocking me from opening important documents that are password protected. I need the latest version to do my day-to-day stuff. Please explain in easy terms as I'm a Linux newbie.
Can someone either tell me how to upgrade manually or get this included as an update?

You've actually fallen in famous X-Y problem loop.
You don't need latest Evince to open password protected pdf. You can just install Foxit reader and make it default PDF viewer. It will gracefully open those pdf.
Download the Foxit reader from here https://www.foxitsoftware.com/downloads/ and install it by double clicking. If that doesn't seem to work, it might be missing executable permission. give it using
chmod +x foxitreader.run
