Pasos para configurar un "local mirror" para ubuntu 14.04LTS
1) Instalar :
sudo apt-get install apache2
sudo apt-get install apt-mirror
2) Cambiar el repositorio de ubuntu.com por uno de España, elegimos el que parece que se actualiza con más frecuencia, encontraremos la información en la página : https://launchpad.net/ubuntu/+archivemirrors
Fichero que editamos :
/etc/apt/mirror.list
