PPA - Personal Package ArchivePublished by admin on Mon, 05/12/2011 - 5:33pm
Using a Personal Package Archive (PPA), you can distribute software and updates directly to Ubuntu users. Create your source package, upload it and Launchpad will build binaries and then host them in your own apt repository.
That means Ubuntu users can install your packages in just the same way they install standard Ubuntu packages and they'll automatically receive updates as and when you make them.
Every individual and team in Launchpad can have one or more PPAs, each with its own URL.
Packages you publish in your PPA will remain there until you remove them, they're superseded by another package that you upload or the version of Ubuntu against which they're built becomes obsolete.
