像我这种一般想起才玩玩BT5的人，跟不上讯息的变化。

　　偶尔想尝试某个实验，然后去安装，发现提示无法找到软件安装包。

　　这个时候，应该注意到，现在已经从BT5到kali了，假如想我这种人，肯定比较少留意软件源地址。原来的BT5的软件源有些已经跟不上了。所以我们应该修改BT5下的软件源

　　vi /etc/apt/sources.list

　　#将下列地址复制进去就好

　　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

　　#然后我们导入公钥

　　sudo apt-key adv –keyserver pgp.mit.edu –recv-keys ED444FF07D8D0BF6

　　#之后我们更新一下，

　　apt-get update

　　上面这个是中科大的软件源

　　下面给出软件源的列表
