Posted 2021-09-29 水香木鱼

1.首先Ctrl+Alt+T打开终端

输入cd /etc/apt/ 输入ls命令看到有一个sources.list文件,备份它:cp sources.list sources.list.old

2.打开阿里云镜像站

[https://developer.aliyun.com/mirror/],找到ubuntu,点击右边的帮助,复制如下软件源代码:(ubuntu18.04自行复制对应版本)

deb http://mirrors.aliyun.com/ubuntu/ xenial main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main

deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe

deb http://mirrors.aliyun.com/ubuntu/ xenial-security main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe

3.用vim打开

sudo vim sources.list

输入ggdG删除所有内容,按i键进入插入模式,鼠标右键粘贴,按Esc切换到命令模式,输入:x回车退出,至此更换镜像源完成.

4.终端输入

sudo apt-get update # 更新镜像源
