Thanks for using apt-mirror.
A small tool that provides ability to mirror any parts (or even all) of Debian and Ubuntu GNU/Linux distributions or any other apt sources which typically provided by open source developers.
On Debian or Ubuntu simply:
$ apt-get install apt-mirror
$ nano /etc/apt/mirror.list
$ sudo apt-mirror
This can then easily be set to run via cron or continued to run manually when you would like to update the mirror.
