1.无法定位软件包

2.此时需要在/etc/apt/sources.list 文件中更新配置源文件，内容如下：

部分源如下（需要把官方源注释掉）：

# 官方源
#deb-src http://http.kali.org/kali/ kali-rolling main non-free contrib
deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib
deb http://http.kali.org/kali kali-rolling main non-free contrib
# 中科大源
deb http://mirrors.ustc.edu.cn/kali kali main non-free contrib
deb-src http://mirrors.ustc.edu.cn/kali kali main non-free contrib
deb http://mirrors.ustc.edu.cn/kali-security kali/updates main contrib non-free
# 阿里云kali源
deb http://mirrors.aliyun.com/kali kali main non-free contrib
deb http://mirrors.aliyun.com/kali sana main non-free contrib

deb-src http://mirrors.163.com/debian-security wheezy/updates main non-free contrib
deb http://mirrors.163.com/debian-security wheezy/updates main non-free contrib

deb http://http.kali.org/kali kali-rolling main non-free contrib

3.配置完成后，输入 sudo apt-get update 更新源：

4.此时提示签名无效，我们需要去下载并安装源对应的签名（此为中科大的签名）：

wget archive.kali.org/archive-key.asc //下载签名
apt-key add archive-key.asc //安装签名

5.下载完成后再次输入 sudo apt-get update 更新源，安装包即可定位
