PackageKit is an open source software project that has been designed as a universal and unified graphical package management system for easy installation, re-installation, update and removal of software packages on a Linux-based computer. It’s main goal is to support as many graphical package managers as possible, making it available on as many GNU/Linux distributions as possible.
Features at a glance
Key features include the ability to install dependency files automatically, install new features, apply security updates at boot, allow unprivileged users to install applications, open unknown file formats, remove dependencies for files, as well as to integrated with existing package managers, including APT, YUM, Conary, and others.
The good thing about PackageKit is that it is independent from a specific Linux kernel-based operating system or a hardware architectures. This means, of course, that it can be easily deployed on any GNU/Linux distribution, but only if the original package manager is supported. It also means that it can successfully be installed on both 64-bit and 32-bit hardware platforms.
Uses PolicyKit for user authentication
Another interesting feature is that PackageKit uses PolicyKit for user authentication, by default, which means that system administrators (root) will be able to easily control who can install what type of software or who is not allows to install software packages on a GNU/Linux operating system where PackageKit is installed.
Supported GNU/Linux distribution and applications
At the moment, PackageKit has been successfully tested with a wide range of GNU/Linux distributions, including Kubuntu, Fedora, openSUSE, Foresight Linux, SUSE Linux Enterprise Server, SUSE Linux Enterprise Desktop, Sabayon and Moblin.
Various projects integrate well with PackageKit, including the Nautilus file manager, GNOME PackageKit package manager, Apper package manager, Listaller package manager, Openmoko Installer package manager, Brasero CD/DVD burning software, Zero Install distributed installation system, system-config-printer CUPS server configurator for Fedora, Anjuta IDE and GNOME Software.
