在使用一些新的payload时，我们会遇到更新msf的需求，可以按如下操作让你的kali随时处于最新状态！
可以这样更新你的metsploit
用leafpad打开，方便复制粘贴：
leafpad /etc/apt/sources.list
然后复制下面的源覆盖原本的：
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 #阿里云kali更新源 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 #163 DEBIAN源 deb http://mirrors.163.com/debian wheezy main non-free contrib deb-src http://mirrors.163.com/debian wheezy main non-free contrib deb http://mirrors.163.com/debian wheezy-proposed-updates main non-free contrib deb-src http://mirrors.163.com/debian wheezy-proposed-updates main non-free contrib deb-src http://mirrors.163.com/debian-security wheezy/updates main non-free contrib
开始更新：
apt-get update apt-get install metasploit-framework
问题1：如果更新时显示update无效的错误！
像这样：
root@kali:~# apt-get update Get:1 http://mirrors.aliyun.com/kali kali-rolling InRelease [30.5 kB] Ign:2 http://mirrors.163.com/debian wheezy InRelease Ign:3 http://mirrors.163.com/debian wheezy-proposed-updates InRelease Err:1 http://mirrors.aliyun.com/kali kali-rolling InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <devel@kali.org>
可以这样操作解决：
root@kali:~# wget -q -O - https://archive.kali.org/archive-key.asc | apt-key add apt-get clean apt-get update
问题2. 如果报：
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
解决如下：
apt --fix-broken install
附：如何更新kali系统：
#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 #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 #清华大学 #deb http://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free #deb-src https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free #浙大 #deb http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free #deb-src http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free #东软大学 #deb http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib #deb-src http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib #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 #重庆大学 #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
保存后之后回到命令行下执行命令：
apt-get update && apt-get upgrade && apt-get dist-upgrade apt-get clean #删除以下载的包 reboot #重新启动
