Debian da depo adresleri /etc/apt/sources.list  de yer almaktadır.

Buradaki depo adreslerini netten bulacağınız depolar ile güncellemek için konsoldan yetkili kullanıcı olarak gedit /etc/apt/sources.list yazarak istediğiniz güncellemeleri yapınız.

Bu işlemden sonra :

apt-get update

apt-get upgrade

komutları ile sisteminizi güncelleyiniz.

Benim internetten bulduğum depo listesi de aşağıdaki gibidir.
