What is a PPA repository?

A PPA is a Personal Package Archive hosted by the ubuntu.com servers that contains binaries and/or source related to a project. The project can be anything from a new application to a backport of an existing one. A good example is the easy availability of OpenOffice.org 3.0.1 to Intrepid users before Jaunty came out rather than having to deal with the mess of packages from Sun’s own website.

PPA’s can be wholly personal to you or may be open to the public. In particular it is very useful for providing Ubuntu packaged versions of a given application instead of dealing with tarballs or converting RPM packages.

So how does one make use of a pre-defined PPA and are there any things to be wary about? Read on.
