x-server crashed after update

[mayankbhagya]

my x-server resulted in a blinking screen after an automatic update followed by a restart on ubuntu-karmic.

i have a nvidia 8400m gs and was running nvidia-185 drivers smoothly until this update happened and asked restart.

while digging deeper, i found that linux-headers and linux-image are half configured packages in dpkg status files and won't let install any other packages too...

I have even tried reinstalling these after removing these packages from dpkg status file. The output of dpkg --configure -a:

$ sudo dpkg --configure -a

This is what happens on 'sudo apt-get -f install':
