I have been using Ubuntu 12.04 for last 4 months. It was working properly but suddenly the Ubuntu software center has started hanging.Now it doesn't open. And every time I try to open it, I have to force quit it. So that I am not able to install the software that I need.I am in a great problem... What do I do? please help me...
I recommend installing the Lubuntu Software Center. It's much faster and I've never experienced a problem with it. If it hangs also then you may have to reinstall your system.
