When we look to keep our Linux computers running like a fine-oiled machine, we usually employ one way or another to keep our systems up to date. For most of us, it's as simple as using the update manager application that comes packaged with our distribution of choice. Or some people prefer to drop to the command line for a good 'ole run-through of our friends "apt get update" and "apt full-upgrade". The point is, for the most part we are diligent folks who run Linux, and we try to do keep our systems tight, fresh, and as updated as possible. All good things, of course.
