Usually this problem is due to installation crash.

in my case it was gxine player which got crashed while updating.

you can see iF,iU etc... which shows that gzine was not installed properly.

so, to fix this problem you just need to execute following command line argument.

sudo dpkg --purge remove gxine

which means remove gzine packet and uninstall the program.

then you can check if the following command gives you responce or not.

sudo dpkg --configure -a

it should work normally...

Hope this helps.

Yes, I can say that this worked fine.

I uninstalled gxine, typed:
sudo dpkg --configure -a

and everything worked as it should.

Thank you.
