使用Ubuntu时，apt-get是很方便的一个工具，但默认使用的欧洲源，国内速度太慢。可以把更新源换成速度更快的镜像，并使用apt-fast去多线程更新。 1、备份更新源文件 $ sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 2、打开更新源文件编辑 $ sudo gedit /etc/apt/sources.list 3、根据UBUNTU版本，把全部内容替换为如下内容 版本11.04 deb http://ubuntu.uestc.edu.cn/ubuntu/ natty main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ natty-backports main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ natty-proposed main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ natty-security main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ natty-updates main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ natty main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ natty-backports main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ natty-proposed main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ natty-security main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ natty-updates main restricted universe multiverse 版本11.10 deb http://ubuntu.uestc.edu.cn/ubuntu/ oneiric main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-backports main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-proposed main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-security main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-updates main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ oneiric main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-backports main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-proposed main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-security main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ oneiric-updates main restricted universe multiverse 版本12.04 deb http://ubuntu.uestc.edu.cn/ubuntu/ precise main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ precise-proposed main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ precise-security main restricted universe multiverse deb http://ubuntu.uestc.edu.cn/ubuntu/ precise-updates main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ precise main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ precise-proposed main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ precise-security main restricted universe multiverse deb-src http://ubuntu.uestc.edu.cn/ubuntu/ precise-updates main restricted universe multiverse 4、更新系统 $ sudo apt-get update $ sudo apt-get dist-upgrade 5、安装apt-fast $ sudo add-apt-repository ppa:tldm217/tahutek.net $ sudo apt-get update $ sudo apt-get install apt-fast 默认使用4个线程下载，可以通过修改/etc/axelrc中的 #num_connections = 4 比如改为10，并去掉前面的"#"将下载线程改为10。 (责任编辑：IT) |
