大家好，又见面了，我是你们的朋友全栈君。

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
