sources.list
sources.list 位于/etc/apt目录下sources.list是一个普通可编辑的文本文件，保存了ubuntu软件更新的源服务器的地址.
2. sources.list.d/*.list
sources.list.d/*.list位于/etc/apt/sources.list.d目录下
为在单独文件中写入源的地址提供了一种方式，通常用来安装第三方的软件.
3. 换源
首先查看自己的Ubuntu系统的codename(这一步很重要)，直接导致你更新的源是否对你的系统起效果，查看方法：lsb_release -a
如果没有 lsb安装下，不过sourcelist出了问题可能也没法安装！！！
No LSB modules are available.
解：
apt install lsb-core -y
解：cat /etc/os-release
4. 镜像源获取
名称分类地址阿里云*xenialhttps://mirrors.aliyun.com/ubuntu/dists/xenial*xenial-backportshttps://mirrors.aliyun.com/ubuntu/dists/xenial-backports*xenial-proposedhttps://mirrors.aliyun.com/ubuntu/dists/xenial-proposed*xenial-securityhttps://mirrors.aliyun.com/ubuntu/dists/xenial-security*xenial-updateshttps://mirrors.aliyun.com/ubuntu/dists/xenial-updates清华*xenialhttps://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/xenial*xenial-backportshttps://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/xenial-backports*xenial-proposedhttps://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/xenial-proposed*xenial-securityhttps://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/xenial-security*xenial-updateshttps://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/xenial-updates中科大*xenialhttp://mirrors.ustc.edu.cn/ubuntu/dists/xenial/*xenial-backportshttp://mirrors.ustc.edu.cn/ubuntu/dists/xenial-backports*xenial-proposedhttp://mirrors.ustc.edu.cn/ubuntu/dists/xenial-proposed*xenial-securityhttp://mirrors.ustc.edu.cn/ubuntu/dists/xenial-security*xenial-updateshttp://mirrors.ustc.edu.cn/ubuntu/dists/xenial-updates
注意：根据codename找.
5. 选择源
ping mirrors.aliyun.com
ping mirrors.tuna.tsinghua.edu.cn
ping mirrors.ustc.edu.cn
6. 备份并修改sources.list
cp /etc/apt/sources.list /etc/apt/sources_init.listvim /etc/apt/sources.listapt update
7. 命令或脚本
1. 命令
格式：sudo sed -i 's/<原域名/新域名>/g' /etc/apt/sources.list
官方源换阿里云源sudo sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list
官方源换清华源sudo sed -i 's/archive.ubuntu.com/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list
官方源换中科大源sudo sed -i 's/archive.ubuntu.com/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
阿里云源换清华源sudo sed -i 's/mirrors.aliyun.com/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list
apt update
2. 脚本
换阿里云源cd /etc/aptvim Init_sources.sh
#!/bin/bash
Codename=$( (lsb_release -a)|awk '{print $2}'|tail -n 1 )
MirrorsName="mirrors.aliyun.com"
echo "\
deb http://$MirrorsName/ubuntu/ $Codename main multiverse restricted universe

deb-src http://$MirrorsName/ubuntu/ $Codename-updates main multiverse restricted universe
">sources.list
apt update
chmod +x Init_sources.shbash Init_sources.sh或./Init_sources.sh
注意:
脚本必须位于/etc/apt目录中.MirrorsName值可以更改为其他镜像的域名.
