很多系统安装好以后都需要进行更新源，或者软件需要更新，小编在这里进行一次更新源和软件的记录，还请路过大牛指出不足。
1、在/etc/apt下有文件sources.list文件，将下方提供的源粘贴一个即可
#命令 vi /etc/apt/sources.list
输入 i 进行编辑，把文章下方附有的kali源粘贴一个即可
2、 执行命令更新源
#命令 apt-get update
3、更新软件并安装
(1)更新软件
#命令 apt-get upgrade 更新所有软件
#命令 apt-get upgrade hydra 更新指定软件，hydra可以为任意软件名
(2) 软件升级安装
#命令 apt-get dist-upgrade
(3) 清理
# apt-get clean
(4) 重启系统
# reboot
