I recently installed kubuntu-desktop in Ubuntu 12.04.

But the problem is that I cannot get some software that I require. I think the reason is that the software repos are the originally provided Gnome Unity Repos and not the Kubuntu repos. When I do

sudo apt-get update
sudo apt-get install package-name

I am not able to install kdm packages because they are not found.

Whereas, I can easily find and install Gnome Unity packages. What should I do install these softwares?

And yes, any general things-after-installing-kubuntu-desktop tips ?

Edit: Let me make myself more clear. I want to install this particular package kdmtheme. But when I do apt-cache search kdmtheme I get no results. I think the reason for this is that, when installing kubuntu-desktop only a few softwares and packages are installed. So what if I want to install any additional KDE software? Since no extra repos are installed while installing kubuntu-desktop I cannot install these via terminal using apt-get, can I? For doing this I will have to add additional software repos of KDE, right?

Where is the screenshot? – Alaa Ali Jul 16 '13 at 12:47
About what kdm packages do you speak? You're wrong with: "I think the reason is that the software repos are the originally provided Gnome Unity Repos and not the Kubuntu repos" – Radu Rădeanu Jul 17 '13 at 6:17
when you install kubuntu-desktop - it just installs the KDE env. on your system, so no repos are deleted, give us the screenshot of your software sources – Rodislav Jul 17 '13 at 6:18
@RaduRădeanu and @Rodislav, what @charlesX is speculating is that the repos for Kubuntu are different from Ubuntu. Is this true? Is the sources.list different in Kubuntu? Or are all Kubuntu-related packages included in the default Ubuntu repos? – Alaa Ali Jul 17 '13 at 6:53
@Alaa I think that the OP just wants to install KDM Theme Manager using apt. – Radu Rădeanu Jul 17 '13 at 7:52

After you install kubuntu-desktop, the repositories and PPAs remain unchanged. Now, I will try to explain why you cannot install what you wish. This happens most often when you give wrong names for the packages. When you don't find a package with apt-cache search <package_name>, try to search for a part of the package name.

In your case, apt-cache search kdm will return something like:

jfsutils - utilities for managing the JFS filesystem
ldm - LTSP display manager
ldm-server - server components for LTSP display manager
kde-workspace-kgreet-plugins - KDE greet libraries for authentication
kdm - KDE Display Manager for X11
kdm-gdmcompat - Provide basic gdm functionality to systems running kdm
kdm-theme-aperture - very glossy Qt4/KDE4 kdm theme - aperture variant

kdm-theme-bespin - very glossy Qt4/KDE4 kdm theme

kdm-theme-tibanna - very glossy Qt4/KDE4 kdm theme - tibanna variant
libpam-usb - PAM module for authentication with removable USB block devices
lxdm - GUI login manager for LXDE
rddmarc - DMARC report processing scripts collection

So, the package name what were you looking for is kdm-theme-bespin. To install it, run in terminal:

sudo apt-get install kdm-theme-bespin

sorry mate, but the kdm-theme-bespin is a theme whereas the kdmtheme is a theme manager. And these 3 themes which appear above in your answer do not appear in my terminal. They are not present in the standard repos provided by ubuntu. They appear in your case maybe because you might have added some extra ppa repo. to ur sources or which might've gotten added when you installed some software! – charlesX Jul 17 '13 at 7:22
@charlesX There is no such a packet in the Ubuntu repositories. You can ask a new question, refering about how to install exactly what you wish. I think I answered at your problem regarding PPA repositories after installing kubuntu-desktop. – Radu Rădeanu Jul 17 '13 at 7:29
@charlesX See There is described how to install KDM Theme Manager and doesn't have nothing to do with Ubuntu's repositories. – Radu Rădeanu Jul 17 '13 at 7:33
yeah, that will work, but I wanted a command-line way of doing it. Or rather an apt way. – charlesX Jul 17 '13 at 7:39
@charlesX There is no apt way since this packet doesn't exist in repositories or in any PPA. – Radu Rădeanu Jul 17 '13 at 7:50
