deb http://mirrors.163.com/ubuntu/ precise main universe restricted multiverse deb-src http://mirrors.163.com/ubuntu/ precise main universe restricted multiverse deb http://mirrors.163.com/ubuntu/ precise-security universe main multiverse restricted deb-src http://mirrors.163.com/ubuntu/ precise-security universe main multiverse restricted deb http://mirrors.163.com/ubuntu/ precise-updates universe main multiverse restricted deb http://mirrors.163.com/ubuntu/ precise-proposed universe main multiverse restricted deb-src http://mirrors.163.com/ubuntu/ precise-proposed universe main multiverse restricted deb http://mirrors.163.com/ubuntu/ precise-backports universe main multiverse restricted deb-src http://mirrors.163.com/ubuntu/ precise-backports universe main multiverse restricted deb-src http://mirrors.163.com/ubuntu/ precise-updates universe main multiverse restricted
