Ubuntu更换国内镜像源

由于Ubuntu官方镜像速度有限，可以使用国内镜像加速更新和下载，节约时间。

常用的国内镜像有很多，本人常用的有如下几个，仅供参考

163镜像

mirrors.163.com

清华镜像

mirror.tuna.tsinghua.edu.cn

中科大镜像

mirrors.ustc.edu.cn

如果要用其他镜像源可以将/etc/apt/sources.list文件中的镜像地址替换为对应源的URL。

以更换163镜像源为例

以20.04(focal)为例,首先将原来的/etc/apt/sources.list文件备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bk

然后将/etc/apt/sources.list文件内容替换为以下内容即可使用

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

如果替换其他版本,需要将其中的focal关键字替换为对应版本的代号,
可以通过lsb_release -cs命令查看,如ubuntu 20.04的代号为focal

ubuntu@ubuntu: ~$ lsb_release -cs
focal
ubuntu@ubuntu: ~$
