PackageKit is a free and open-source suite of software applications designed to provide a consistent and high-level abstraction layer for a number of different package management systems.
PackageKit was created by Richard Hughes in 2007,[2][3] and first introduced into an operating system as a default application in May 2008 with the release of Fedora 9.
[4] The suite is cross-platform, though it is primarily targeted at Linux distributions which follow the interoperability standards set out by the freedesktop.org group.
It uses the software libraries provided by the D-Bus and Polkit projects to handle inter-process communication and privilege negotiation respectively.
PackageKit seeks to introduce automatic updates without having to authenticate as root, fast-user-switching, warnings translated into the correct locale, common upstream GNOME and KDE tools and one software over multiple Linux distributions.
