Medibuntu if you don’t already know is the Ubuntu repository for non-free packages which can’t be bundled with Ubuntu for regal reasons. Acrobat reader, quick time player, windows specific video/audio codecs, DVD support and the list goes on.

Adding the Medibuntu repository into your Ubuntu 8.10 is easy.

  1. Fire up your terminal and run,
sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list
  1. Install the GPG keys. While still in the terminal run,
sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update
  1. Install support for Windows codecs.

sudo apt-get install w32codecs
