由於中國特色網絡環境，我們必須對lkali2的源進行一下更改，這樣速度會比較快。
Look here！
首先，尋找幾個國內源：
#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 #阿里雲 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 #清華大學 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 #東軟大學 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
ok，下一步：
ctrl+alt+T 啟動Terminal
然后 vim /etc/apt/sources.list
將上面的源copy到里面就行了
這樣源就切換了，然后就是
apt-get update
apt-get upgrade
apt-get dist-upgrade
。。。。。。。。
最后reboot，美滋滋。。。。。。。
