When I click on Ubuntu Software Center it does nothing. Would you please help to get it working?

Also I tried update & upgrade, but no use. I tried it via terminal using software-center then it gives this error.

i have installed a Zope module from some other source than the official repository, to fix this i run the following commands:

cd /usr/local/lib/python2.7/dist-packages/zope
sudo ln -s /usr/share/pyshared/zope/interface/

Source: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1085425

now it works for me. :D
