Ubuntu and Amazon on Demand – Make it Work

Running into this error when trying to watch Amazon on Demand on Ubuntu?

An error occurred and your player could not be updated.  
This is likely because your Flash Player or Browser needs to be updated.
This update is required to play back this video.

You’re not alone.  To get Amazon on Demand to work with Ubuntu 13+, close your Firefox browser, then run the following commands and restart firefox:

sudo add-apt-repository ppa:mjblenner/ppa-hal
sudo apt-get update
sudo apt-get install hal

Why this works: Ubuntu deprecated HAL from 13.10 forward. HAL is required by flash to run DRM protected content (such as Amazon on Demand), so we use a custom PPA to get everything working as before.
