PackageKit is a free and open-source suite of software applications designed to provide a consistent and high-level front end for a number of different package management systems PackageKit was created by Richard Hughes in 2007,23 and first introduced into an operating system as a default application in May 2008 with the release of Fedora 94
The suite is cross-platform, though it is primarily targeted at Linux distributions which follow the interoperability standards set out by the freedesktoporg group It uses the software libraries provided by the D-Bus and Polkit projects to handle inter-process communication and privilege negotiation respectively
Since 1995, package formats have been around, since 2000 there have been dependency solvers and auto-downloaders as a layer on top of them around, and since 2004 graphical front-ends 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 distributions5

PackageKit itself runs as a system-activated daemon, packagekitd, which abstracts out differences between the different systems A library called libpackagekit allows other programs to interact with PackageKit6
- installing local files, ServicePack media and packages from remote sources
- authorization using Polkit
- the use of existing packaging tools
- multi-user system awareness – it will not allow shutdown in critical parts of the transaction
- a system-activated daemon which exits when not in use
Graphical front-ends for PackageKit include:
Apper uses Qt
GNOME Software uses GTK+
gnome-packagekit is obsoletedcitation needed
pkcon operates from the command-line7
A number of different package management systems known as back-ends support different abstract methods and signals used by the front-end tools8 Back-ends supported include:
- Advanced Packaging Tool APT
- hawkey9 & librepo,10 the libraries upon which DNF, the successor to yum builds
- Smart Package Manager
- Red Carpet
- Software Updater
