kali linux修改更新源
1、修改sources.list源文件：
leafpad /etc/apt/sources.list
可以参考下面的源：
#aliyun 阿里云
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
# ustc 中科大
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
#deb http://mirrors.ustc.edu.cn/kali-security kali-current/updates main contrib non-free
#deb-src http://mirrors.ustc.edu.cn/kali-security kali-current/updates main contrib non-free
# kali 官方源
deb http://http.kali.org/kali kali-rolling main non-free contrib
deb-src http://http.kali.org/kali kali-rolling main non-free contrib
# 默认的，可以注释掉不用管
#deb http://security.kali.org/kali-security kali-rolling/updates main contrib non-free
#deb-src http://security.kali.org/kali-security kali-rolling/updates main contrib non-free
笔者用的是中科大的源：
# ustc 中科大
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
#deb http://mirrors.ustc.edu.cn/kali-security kali-current/updates main contrib non-free
#deb-src http://mirrors.ustc.edu.cn/kali-security kali-current/updates main contrib non-free
2.更新一下源：
apt-get update
3.更新软件
ape-get upgrade
4.更新系统
apt-get dist-upgrade
5.清理安装包
apt-get clean
apt-get autoclean
安装过程中，均按默认安装即可~
安装完成之后，重启就可以用啦！
