Hi dipanshu, and thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. Is there an issue other than the warning message that you pasted in the description (this warning is just that, a warning as is not serious and Software Center will continue to work fine despite that). If you are, however, encountering additional symptoms besides this message, please add the following to this bug so that we can help to determine the steps to fix:
1. the specific steps or actions you took that caused you to encounter the problem, 2. the behavior you expected, and 3. the behavior you actually encountered (in as much detail as possible). Thanks! When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.
