Trying to add the KDE desktop

[Jose Medeiros]

Greetings,

Quick question for all you Linux and KDE Guru's. I installed Ubuntu on
my AMD 64 CPU using 5.10 and I am trying to add the KDE desktop using
the following commands, any ideas why it is not finding the correct
package?
-------------------
jose at sg3:~$ sudo apt-get install kubuntu-desktop
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package kubuntu-desktop
jose at sg3:~$ sudo apt-get install kubuntu-desktop
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package kubuntu-desktop
jose at sg3:~$ sudo apt-get install kde

Thank you in advance!

Jose :-)
