What is Dpkg?
DPKG is the software at the base of the package management system in the free operating system Debian and its derivatives. It is currently used to install, remove, and provide information about Debian packages; eventually, it will be used to manage any kind of binary or source package. It was first released as a separate program (dpkg) alongside the old .deb packaging format to enable it to run on non-Debian systems, but has since become an integral part of .deb processing.
What is Ubuntu?
Ubuntu is a Linux-based operating system that runs from the desktop, to the cloud, to all your internet connected things in between. Perfect for home users, students and hackers alike, its easy-to-use interface puts you in control of your machine. Users can run Ubuntu on a computer, or in a virtual machine on top of their existing operating system. There are three editions: 'Ubuntu Desktop Edition' for personal computers, the 'Ubuntu Server Edition', and the lightweight 'Ubuntu Core' edition for embedded devices and appliances.
