Fedora 20 (codename Heisenbug) Beta was released on November 12th 2013. One of the accepted system wide change proposals for this release was to replace the existing gnome-packagekit frontends (gpk-update-viewer and gpk-application) with a new unified and more user-centric application. A quick high-level overview of PackageKit first. It is essentially a framework which consists of frontends such as yum which communicate with backends such as PackageKit-yum via an abstraction layer based on D-Bus. Essentially, it is a set of APIs exported through a D-Bus interface. Glib, qt and python and other language bindings are available. This abstraction layer enables applications

PackageKit uses an abstraction layer to allow a session user to manage software packages in a secure way. This abstraction layer is based on D-Bus. Essentially, it is a set of APIs exported through a D-Bus interface. Glib, qt and python and other language bindings are available. This abstraction layer enables applications to perform high-level package operations such as add or remove a package without having to know much about package management. PolicyKit (AKA PolKit) is incorporated to provide a fine grained policy mechanism for users. D-Bus has two connections types (buses): System and Session. System interfaces normally run as PackageKit is essentially a framework which consists of frontends such as yum which communicate with backends such as PackageKit-yum via an abstraction layer based on D-Bus.

PolicyKit (AKA PolKit) is incorporated to provide a fine grained policy mechanism for users. PackageKit is not Fedora-specific. A number of Linux distributions use it. PackageKit was A couple of months ago, the PackageKit utility on my Fedora 18 system stopped working. YUM continued to work so I had an easy workaround and did not really try to trace down the problem and fix it. I assumed that a future version of a PackageKit RPM would fix the problem. Recently I did a FedUp upgrade to Fedora 19 and the problem persisted so I decided the time had come to investigate the root cause of the problem and fix it. Here is how the problem manifested itself: A quick check of Fedora Bugzilla convinced me that the |
