Debian系统修改软件源

在修改源之前需要先知道当前系统的版本，查看系统版本执行命令lsb_release -a

查看系统版本

# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:        11
Codename:       bullseye

若提示bash: lsb_release: command not found则需要先安装lsb-release

# apt-get install lsb-release

在确定系统版本后，找到对应的源地址，一般我们就使用163的源就可以了，直接修改/etc/apt/sources.list文件

修改源地址

# vi /etc/apt/sources.list
deb http://mirrors.163.com/debian/ bullseye main non-free contrib
deb http://mirrors.163.com/debian/ bullseye-updates main non-free contrib
