我的特技就是全身上下都能吃

tw.archive.ubuntu.com 這台伺服器似乎在 7/30 左右掛點，一直到現在都連不上。
先將伺服器改到 archive.ubuntu.com

#sudo vim /etc/apt/sources.list

然後將所有 tw.archive.ubuntu.com 取代為 archive.ubuntu.com
或是加上：

deb http://archive.ubuntu.com/ubuntu/ jaunty main restricted
deb-src http://archive.ubuntu.com/ubuntu/ jaunty main restricted
deb http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted
deb-src http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted
deb http://archive.ubuntu.com/ubuntu/ jaunty universe
deb-src http://archive.ubuntu.com/ubuntu/ jaunty universe
deb http://archive.ubuntu.com/ubuntu/ jaunty-updates universe
deb-src http://archive.ubuntu.com/ubuntu/ jaunty-updates universe

儲存以後下：

#sudo apt-get update
#sudo apt-get upgrade
#sudo apt-get dist-upgrade
