1.更換源
首先在終端輸入
vim /etc/apt/sources.list
#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
編輯源之后，apt-get update && apt-get upgrade && apt-get clean ,更新好源和更新軟件
2. 在命令行輸入”dpkg-reconfigure locales”。進入圖形化界面之后，（空格是選擇，Tab是切換，*是選中,PgDn是向下翻一頁），選中zh_CN.UTF-8，確定后，將zh_CN.UTF-8選為默認。
3.安裝中文字體
apt-get install xfonts-intl-chinese
apt-get install ttf-wqy-microhei
這時候就完成了
在命令行輸入reboot重啟就好了
也可以添加別的源：
#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
在終端中使用kali-undercover可以在兩個主題之間切換。
