Snapping Synaptic

Repeated attempts to uninstall unwanted applications by using Synaptic end with the error - rpm databse not found. Unlike most Windows applications with an "uninstall" or "unwise" program that can be run to uninstall applications, I am not able to find a similar executable for programs installed in the Linux system. Programs mostly end up under the /usr/bin folder.

In general, application misfires are not a rare event in Linux. It is expected that every boot brings something new to the equation. It is not surprising to have a system that worked fine during the last session to exhibit inexplicable anomalies at the next boot. Most of these anomalies disappear on a restart, though.
I would like to believe that these problems arise out of the absence of tight integration between different components that constitute a disto. It is rare for all applications in a distro to have the same creator. Since all distros are a bundle of different apps, it is expected that the interfacing between all these apps across different environments would not have passed rigorous quality tests.
