kali linux更换源

1. 切换到root用户：sudo su

2. 更改源:

vim /etc/apt/sources.list

阿里源：

deb http://mirrors.aliyun.com/kali kali-rolling main non-free contrib
deb-src http://mirrors.aliyun.com/kali kali-rolling main non-free contrib

中科大源：

deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib
deb-src http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

如下图：将阿里源或中科大源，复制粘贴到sources.list文件内。

3，更新系统

sudo apt update

sudo apt upgrade

sudo apt dist-pugrade
