Ritesh, It says an exclusive lock is not available, or something similar. I did not try apt-get clean.

I am not aware of the latter error message. Did you try apt-get clean, apt-get update and then run update-manager -d? If you have a separate /home partition or can back up your data, I would recommend that you do a fresh install which is bound to be less error-prone.
