Ubuntu Software Center does not open, I tried these instructions to fix it but they didn't work https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure When I run software-center command from a bash terminal, it still give me the next error.

I found that this error was produced after install google-api-python-client using this command:
sudo easy_install --upgrade google-api-python-client
It seems that it messed up with some httplib. I still don't know how to correct this error (or install this package correctly). I had to reinstall Ubuntu and do not install the api to avoid the problem.
I would be grateful if someone could help me.
