What is Kubuntu?
The Kubuntu distribution is a spin-off from Ubuntu, which aims to create a new user-friendly desktop system using the Linux operating system. Kubuntu comes with the KDE Plasma Desktop Environment installed by default and provides users with similar functionality and visual appearance (a 'look-and-feel') to other current popular operating systems such as Windows XP and Apple's Mac OS X.
What is Nexus?
The Nexus repository is a repository that facilitates the discovery, access and installation of public artifacts. It supports open source dependencies and references them in Maven-compatible package declarations. The most common use is to resolve a target dependency by hashing a file with a specified MD5 sum and using Nexus to look up the artifact in its local cache or available repositories . It is also possible to combine Maven (and other) metadata with an artifact before publication.
