Posted 2021-12-16 山川绿水

Ubuntu 换源

一、运行环境
VMware WorkStation 15.5 Pro
Ubuntu-20.04-desktop-amd64

二、实操应用

1.备份原始文件

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

2.修改配置文件

vim /etc/apt/sources.list

如果是报以下错，说明你没有安装vim

3.先下载好vim编译器，如果你已经安装好vim，可以跳过这一步

apt-get install vim

4.安装好vim以后，修改里面的内容

vim /etc/apt/sources.list

使用#注释掉前面所有的内容，在后面加上

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

5.更新源

sudo apt-get update

6.更新软件

sudo apt-get upgrade
