Please refer to the attached screen-shot. This error comes every time I boot and now I am unable to get any updates.
Also, the Ubuntu Software Center will no longer work. I click on the USC icon and nothing happens.

I am using Maverick Meercat Netbook. Please advise how to resolve this problem.
Thanks for your help.
