Warning: Since some time, this article need the Gutsy backports to be enabled. This can be done with the following command line :

/usr/bin/sudo /bin/sed -i -e 's/^#[ ]*\(.*gutsy-backports.*\)$/\1/' /etc/apt/sources.list

Fast and obfuscated

The following command lines summaries this guide. First, you need to initialize your sudo environment :

sudo echo

Then copy / paste the following lines in your terminal to install Audacious Media Player 1.4 :

echo "# Morgoth gutsy backports
# Contains Audacity 1.4
deb http://morgoth.free.fr/ubuntu gutsy-backports main
deb-src http://morgoth.free.fr/ubuntu gutsy-backports main" \
    | sudo tee /etc/apt/sources.list.d/gutsy-morgoth-backports.list
/usr/bin/wget http://morgoth.free.fr/files/morgoth-signkey.gpg.asc -O- | sudo /usr/bin/apt-key add -
sudo apt-get update
sudo apt-get -y install audacious audacious-plugins audacious-plugins-extra

Install

Note : If you have already followed this guide, i encourage you to remove the dereferenced repositories from your apt configuration :

sudo /bin/rm /etc/apt/sources.list.d/gutsy-dereferenced-universe.list

We add the Morgoth repository to our apt configuration :

echo "# Morgoth gutsy backports
# Contains Audacity 1.4
deb http://morgoth.free.fr/ubuntu gutsy-backports main
deb-src http://morgoth.free.fr/ubuntu gutsy-backports main" \
    | sudo tee /etc/apt/sources.list.d/gutsy-morgoth-backports.list

We trust the key signing this repository :

/usr/bin/wget http://morgoth.free.fr/files/morgoth-signkey.gpg.asc -O- | sudo /usr/bin/apt-key add -

We update the list of available packages :

sudo apt-get update

And we install Audacious and its plugins.

sudo apt-get install audacious audacious-plugins audacious-plugins-extra
