Got error while installing KDE 4.11 from kubuntu backport repo !

[Navdeep Singh Sidhu]

Hello,

Today i was installing KDE lastest version from kubuntu backports on my
fresh installed ubuntu 12.04.03 64 bit (softpedia tutorial). but first i
got error that it has missing dependencies. then i disabled backport repos
and installed Kubuntu-desktop. It got successfully installed.

then restarted my computer after performing an upgrade into KDE and remove
d all unity packages with
apt-get purge unity*

So far no error. But then i tried to install latest kde by enabling
backport repo and during installation i got this error.
