Hello narendra.d and welcome to the forum, I hope you enjoy LMDE. I hope also that as an LMDE user you have subscribed to this thread:viewtopic.php?f=141&t=67502
it is the most important source of information that LMDE users have about the multitude of updates that accompany this distro, and although it isn't being properly administered at the moment (because it is being left to one user instead of being the responsibility of the whole LMDE team) it is still a vital source of info. Always check it before you update your system unless you are very confident of being able to fix your own problems.
On another topic entirely, congratulations on beating Australia today (or are you the only person in India that doesn't like cricket?)
