I am fairly new to Ubuntu and I have some problems. My Ubuntu version is 11.10. For some time now, the Ubuntu software center hasn't been working (when I click on it, it lights up a bit, as if it will start, but nothing happens), and installing from the terminal does nothing as well. Whatever I try to install that way, I get the message:
Reading package lists... Done
Building dependency tree... 0%
And then it kind of freezes.
Both the installer and the software center have been working fine before, but I have no idea when they stopped, or what I did to make them this way... Does anyone have any idea how I can fix them?
