Installing VLC Media Player

In Ubuntu Maverick Meerkat 10.10 the Graphical way:

Open Synaptic application
Click on System -> Administration -> Synaptic Package Manager.
In Settings -> Repositories, make sure you have an universe repository activated.
Search for vlc and install it. You should install vlc-plugin-pulse and mozilla-plugin-vlc as well.
If we are interested in streaming or trans-coding, we should additionally install:
libavcodec-extra-52 from a multiverse repository.

Command line way:

First check that a universe mirror is listed in your /etc/apt/sources.list file. If not add it. Now Open Terminal (Ctrl+Alt+T) and type:

sudo apt-get update
sudo apt-get install vlc vlc-plugin-pulse mozilla-plugin-vlc
sudo apt-get update
sudo apt-get upgrade
