Ubuntu installer problems

Question

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?

Answer 1

If you familiar with the Terminal, try:

sudo apt-get update

and see what happens or errors. It should update your package list. Apt-get is a command line software center.
