Failed to install

Hi to all,
I am in China and I just followed the instructions reported here:
http://www.nginx.org/en/download.html
but after running the “sudo apt-get update” command I get the following
error:

W: Impossibile recuperare
http://nginx.org/packages/debian/dists/quantal/nginx/source/Sources 404
Not Found

W: Impossibile recuperare
http://nginx.org/packages/debian/dists/quantal/nginx/binary-i386/Packages
404
Not Found

E: Impossibile scaricare alcuni file di indice: saranno ignorati o
verranno usati quelli vecchi.

What can I do?
Thanks.
Kubuntu 12.10

Please, check your “/etc/apt/sources.list”.

It looks like you have confused ubuntu with debian.
