網友可自己訪問： http://mirrors.163.com/.help/ubuntu.html 里面詳細說明， 支持最新的 Ubuntu 14.04。
以trusty(14.04)為例, 編輯/etc/apt/sources.list文件, 在文件最前面添加以下條目(操作前請做好相應備份)：
deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse
然后執行 sudo apt-get update 獲取新的軟件列表。下載一個 open jdk，比原來的快很多， 幾分鍾就下完了。
