1.更换源
首先在终端输入
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
编辑源之后，apt-get update && apt-get upgrade && apt-get clean ,更新好源和更新软件
2. 在命令行输入”dpkg-reconfigure locales”。进入图形化界面之后，（空格是选择，Tab是切换，*是选中,PgDn是向下翻一页），选中zh_CN.UTF-8，确定后，将zh_CN.UTF-8选为默认。
3.安装中文字体
apt-get install xfonts-intl-chinese
apt-get install ttf-wqy-microhei
这时候就完成了
在命令行输入reboot重启就好了
也可以添加别的源：
#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
在终端中使用kali-undercover可以在两个主题之间切换。
