What causes packages not to be updated?

[Dotan Cohen]

Why would apt-get not update a package that I explicitly ask it to?
How can I check what is wrong?

ubuntu at ubuntu-desktop:~$ sudo apt-get update
Get:1 http://security.ubuntu.com feisty-security Release.gpg [191B]

ubuntu at ubuntu-desktop:~$

Thanks in advance.
