Pd-vanilla and a number of libraries are included, so you can install using Synaptic, Ubuntu Software Center, and apt-get install. The official packages are called puredata, gem, pd-zexy, pd-aubio, pd-csound, etc. All of the libraries start with pd-

For Pd-extended releases, use the apt.puredata.info repository. To add it, run these command in your Terminal:

 sudo add-apt-repository "deb http://apt.puredata.info/releases `lsb_release -c | awk '{print $2}'` main"
 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key 9f0fe587374bbe81
 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key D63D3D09C39F5EEB
 sudo apt-get update
 sudo apt-get install pd-extended

You can also now find the package pd-extended in Synaptic or Ubuntu Software Center.

Getting Individual Libraries

It is also possible to get individually packaged libraries that are included in the official repos, but built for older releases. These packages are in the eighthave/libdirs PPA on launchpad.net. Some of the packages go back as far as Ubuntu/karmic 09.10.

Getting the Pd-extended Beta Build

You can also use a repository for getting pre-release builds of Pd-extended using the Pd-extended PPA. To add it, run these command in your Terminal:

 sudo add-apt-repository ppa:eighthave/pd-extended
 sudo apt-get update
 sudo apt-get install pd-extended

You can also now find the package pd-extended in Synaptic or Ubuntu Software Center.
