I uninstalled Ariya in Kubuntu, how do I install it again?

Question

I have installed Kubuntu 12.04 LTS. By mistake, I removed default login screen (Ariya). It is now showing this message:

Cannot login /user/shared/kde4/apps/kdm/themes/ariya

Now I am not able to login to previous GUI. It is getting login in command line.

How to resolve problem?

Answer 1

$ mkdir kdm && cd kdm
$ sudo apt-get source kdm

And in the unpacked package folder you will find KDM with the Ariya files included.

Here goes nothing (aka. the apt-file utility):

You can find contents in packages with "apt-file". It's an application, you have to install it. Then run the apt-file update command as a single user. And then, you can search.
With: apt-file find ariya

Another way if this one fails (the almighty --reinstall flag):
Just use the --reinstall flag with apt-get.
sudo apt-get install --reinstall kdm
