The sources.list of a fresh-installed Ubuntu is using the host of "http://archive.ubuntu.com", which is really slow for some country.
And the default "Server for XXX" is sometimes not the best of all servers.
For example, for Taiwan, the free.NCHC.org mirror is the fastest, but the mirror:// protocal doesn't think so.
So please add a secion/option like default_ppa to replace the default repo into the specified one.
In other words,
automatically change /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu precise-proposed restricted main multiverse universe
...
to
deb http://free.nchc.org.tw/ubuntu/ precise-proposed restricted main multiverse universe
