ubuntu修改镜像源

查看ubuntu版本号

1	cat /proc/version

1.简单方法

使用sed命令进行替换。

这里是北外的源

sudo sed -i s@/archive.ubuntu.com/@/mirrors.bfsu.edu.cn/@g /etc/apt/sources.list
sudo sed -i s@/security.ubuntu.com/@/mirrors.bfsu.edu.cn/@g /etc/apt/sources.list
sudo apt-get clean
sudo apt-get update

这里是阿里云的

sudo sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list
sudo sed -i s@/security.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list
sudo apt-get clean
sudo apt-get update

中科大一键更新ubuntu

sudo sed -i s@/archive.ubuntu.com/@/mirrors.ustc.edu.cn/@g /etc/apt/sources.list
sudo sed -i s@/security.ubuntu.com/@/mirrors.ustc.edu.cn/@g /etc/apt/sources.list
sudo apt-get clean
sudo apt-get update

2.手动修改

Ubuntu 的软件源配置文件是 /etc/apt/sources.list。将系统自带的该文件做个备份，将该文件替换为下面内容，即可使用选择的软件源镜像。

这里以ubuntu22.04为例
