I was trying to install Amarok 1.4 on Ubuntu 12.04 (Gnome-classic), by following this instructions. Problem started after giving these two commands

dpkg -i kdelibs5-data_4.6.2-0ubuntu4_all.deb

dpkg -i kdelibs-data_3.5.10.dfsg.1-5ubuntu2_all.deb

Now, immediately after these commands, Ubuntu Updater popped up and gave me an error that the package catalog is broken and needs to be repaired. Nothing can be installed or removed till then. It also offered a suggestion to run apt-get install -f.

I tried that, but again got the same error.Also tried apt-get clean followed by apt-get

install -f.
Again got the following output:

jitesh@jitesh-desktop:~$ sudo apt-get clean
jitesh@jitesh-desktop:~$ sudo apt-get install -f

As I thought the error was related to configuring kdelibs, I tried to configure using dpkg. But got the following errors:

jitesh@jitesh-desktop:~$ sudo dpkg --configure -a

Now I dont have any idea how to proceed. I am unable to install anything from Software Centre or using Terminal now.

Some basic info: Core2Duo, dual booting Ubuntu 12.04 with Win7. Fresh install of Ubuntu 12.04 (not upgrade). Incidentally, I had first upgraded from 10.04 and had succesfully installed Amarok 1.4 following this same method. But due to other issues, i had to format and do a clean install of 12.04. Now when I tried to install Amarok 1.4, I'm getting these errors. I also have digiKam and k3b installed, if that can be of any help. I use digiKam a lot, so removing KDE is not feasible for me.

Any help on this issue will be highly appreciated. Thanks in advance.
