先在在终端输入sudo gedit /etc/apt/sources.list 把里面的源，换成以下： deb http://archive.ubuntu.com/ubuntu/ gutsy main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ gutsy-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ gutsy-updates main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ gutsy-proposed main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ gutsy-backports main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ gutsy main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ gutsy-security main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ gutsy-updates main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ gutsy-proposed main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ gutsy-backports main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu/ gutsy main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu/ gutsy-security main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu/ gutsy-updates main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu/ gutsy-proposed main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu/ gutsy-backports main restricted universe multiverse deb-src http://ubuntu.cn99.com/ubuntu/ gutsy main restricted universe multiverse deb-src http://ubuntu.cn99.com/ubuntu/ gutsy-security main restricted universe multiverse deb-src http://ubuntu.cn99.com/ubuntu/ gutsy-updates main restricted universe multiverse deb-src http://ubuntu.cn99.com/ubuntu/ gutsy-proposed main restricted universe multiverse deb-src http://ubuntu.cn99.com/ubuntu/ gutsy-backports main restricted universe multiverse deb http://ubuntu.cn99.com/ubuntu-cn/ gutsy main restricted universe multiverse 然后再在终端输入sudo apt-get dist-upgrade 然后 在 system->administration->language support 选 择安装语言 .....然后 我 等 了 好久才 装 完 .要 半个 小时.
