Installing KDE Software Compilation on an Ubuntu system.
How to Install
There are different packages to be installed to acquire Kubuntu from an Ubuntu installation depending on which packages you want. Below are the three possible choices, or "routes", to go down; the packages below are metapackages -- they depend upon other, "real", packages, and with their installation they pull them in. For details on package installation methods, see the wiki page InstallingSoftware. The options are as follows:
(i) kubuntu-desktop -- This is the recommended metapackage to install; the full Kubuntu installation, with all the Kubuntu recommended packages. This includes LibreOffice, Kontact, Konversation, Amarok, K3B, and others.
(ii) kde-full -- This will install the following KDE packages: kdegames, kdeaccessibility, kdeaddons, kdeadmin, kdeartwork, kdegraphics, kdemultimedia, kdenetwork, kdepim, kdesdk, kdeutils, kdewebdev, and the kde-plasma-desktop metapackage (see details below).
(iii) kde-plasma-desktop --- This will install the core -- the bare-minimum required-- of KDE. That is, kdebase-apps, kdebase-runtime, kdebase-workspace and kdm.
If you choose to not install kubuntu-desktop, then you can still get all the Kubuntu-specific tweaks by installing the kubuntu-default-settings package. For users with GTK applications, you will need the kde-config-gtk-style and/or gtk3-engines-oxygen package(s) installed, if they aren't already, for proper integration.
Other Recommended Packages
Also, here are a few other recommended packages if you do not choose to go down the first route:
Amarok -- A full featured music player for KDE
Muon -- A new Kubuntu specific Package installer, if you install Muon you will also need polkit-kde-1 so it will request elevated privileges (or else it will fail to install anything).
Kpackagekit -- The default cross distro package installer
Konversation -- An IRC Client for KDE.
