I'm running newly installed Ubuntu 12.04 in my computer.
After the command
sudo apt-get update, my terminal shows the following message:
Reading package lists... Done
After that, nothing happens. What's wrong?
There is nothing wrong with your system:
sudo apt-get update will only update the package list.
To really update packages, you have to type:
sudo apt-get upgrade afterwards as well!
let me add to this that
sudo apt-get upgrade will finish with
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded if you already have installed all latest updates. When you already have installed all updates for your system,

x packages have been kept back, you should run
sudo apt-get dist-upgrade.

If so, Ubuntu Sources List Generator helps you get a default sources.list.
This Generator right now supports version later than 12.04.
If you are thinking of only updating, you can as well do it by using update manager.
