What is the difference between kubuntu-desktop, plasma-desktop and
apt show on each:
- Description: Kubuntu Plasma Desktop/Netbook system
- Description: KDE Plasma Desktop and minimal set of applications
- Description: Tools and widgets for the desktop
Look at the depends for each in the output of each
apt show command to know more.
In brief, kubuntu-desktop provides a fuller KDE Plasma desktop experience relative to that obtained by installing kde-plasma-desktop.
It's a bit like installing xubuntu-desktop versus xfce4.
By the way, kubuntu-full provides even more packages than kubuntu-desktop.
I don't know the basis for the question, but I prefer not mixing desktop environments. Other users seem to handle multiple desktop environments just fine.
