Kubntu is based on Ubuntu but it is quite different in terms of Graphical User Interface. Ubuntu has the Unity based graphical environment (GNOME desktop environment developed by Canonical Ltd.) where as Kubuntu uses KDE Plasma Desktop instead for graphical user interface. KDE Plasma 4 and 5 provide an environment for creating and running applications. KDE Plasma 4 is the umbrella term for 4th generation graphical environments. KDE Plasma 5 was then released on July, 2014 as its successor. KDE Plasma has many components, KDM, KWin, Plasma core libraries, System settings etc.
Kubuntu 15.04 (Vivid Vervet) has Plasma 5 which will pleasantly surprise the end users. It is important to note that if you don’t upgrade Kubuntu to the latest version, system will be stuck with iterations of Plasma 4 branch and it is no more supported.

Few Things to do after installing Kubuntu 15.04 (Vivid Vervet)
System Update: It is very important to update your system even after a fresh installation. There may have been few patches released/implemented for newly detected threats or vulnerabilities. Open Moun update manager and install all the available updates.
Update Package Manager: Although Moun discover is a very nice package manager shipped with Kubuntu by default but there are few others which can perform even better, especially in terms of resolving dependancies. For example, Apper or Synaptec. You can install these through terminal using following commands.
sudo add-apt-repository ppa:snwh/pulp
sudo apt-get update && sudo apt-get install apper
sudo apt-get install synaptic
Install/Update Ruby: Install Ruby if not already done or upgrade it to latest version using apt-get package manager from terminal. You can also use Apper or Synaptec package managers to install/upgrade Ruby and its gems through GUI.
Sudo apt-get install ruby rubygems
Enhancements in Terminal: Those who love working in terminal would love the drop-down terminal Yakuake. It can be installed through Moun ackage manager or any other we installed earlier. Yakuake can easily be navigated/hidden through F-12 Key.
File Managers: Dolphin is the default file manager for vivid vervet. One very good thing that ruby can help here is to open the folders with root permissions.
Krusader is another very nice file manager which can be installed through any package manager. Use following command to install Krusader through terminal.
sudo apt-get install Krusader
Krusader has a very useful split window view which can help in comparisons, synchronizations etc. Furthermore it supports FTP, SAMBA, etc.
KDE Plasma 5.3 was released this morning Tuesday, 28 April 2015 and you can update repository via Muon tool (To open it, click on your Kmenu, then open Muon) or command line as below to install new version of Plasma.
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update && sudo apt-get dist-upgrade
