网站的超级链接怎么做网络营销策划方案ppt

原因：

国内源的地址大部分都是http开头，这些地址早就无法使用。

解决方案：

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

另外，需要kali Linux更换最新的源地址：

vim /etc/apt/sources.list

#官方源
deb http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware
deb-src http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware#阿里云
deb https://mirrors.aliyun.com/kali kali-rolling main non-free contrib
deb-src https://mirrors.aliyun.com/kali kali-rolling main non-free contrib#清华大学
deb https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main non-free contrib
deb-src https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main non-free contrib#中科大
deb https://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

输入以下命令进行更新：

更新软件列表(非root权限在命令行前加sudo)，时间可能较长，我这里只更新索引

apt-get update 更新索引

apt-get upgrade 更新软件

apt-get dist-upgrade 升级

apt-get clean 删除缓存包

apt-get autoclean 删除未安装的deb包
