• 软件源

kali linux 的软件源文件在：

/etc/apt/sources.list

可以用leafpad打开，在终端中键入：

leafpad /etc/apt/sources.list

在这个文件中#是注释，原码是kali官方的软件源，更换国内软件源的话，在速度上可能会快一些。但是我自己换了几个国内的源，都不好用，要不就是不能定位软件包，要不就是什么仓库问题。所以我建议还是用官方源吧，虽然也遇到一些问题。下面我放上主流国内的源。

用法：直接复制到source.list 里面，记得把官方源前面加#，用那个源，就把它前面的#去掉。

• 软件更新

一般的一次整体更新软件需要以下几步：

apt-get       update #更新源

apt-get        upgrade #更新已经安装的软件包

apt-get         dist-upgrade #升级系统

apt-get         clean #清除

几种常用的操作

删除下载的软件包

apt-get         clean #清除 /var/cache/apt/archives目录

安装本地软件包

dpkg          -i                package_name.deb #安装本地软件包，不解决依赖关系

移除本地软件包

dpkg          -r         package #删除软件包

dpkg         -P             #删除软件包及配置文件
