解决方案 #

我之前碰到过完全一样的问题，试了下面几个方法就解决了，你可以挨个试试：

• 将HTTP源替换为HTTPS
  Kali官方现在逐渐不再支持HTTP访问源仓库，HTTP请求会被直接返回403。修改源配置文件的步骤如下：

  1. 打开终端执行：sudo nano /etc/apt/sources.list
  2. 把文件里所有以http://开头的源地址替换成https://，比如把http://kali.download/kali改成https://kali.download/kali
  3. 按Ctrl+O保存，回车确认后，再按Ctrl+X退出编辑器
  4. 重新执行sudo apt update，看看是否解决问题

• 更换为国内镜像源
  如果官方源访问还是有问题，可以试试国内的镜像源，比如清华镜像：

  1. 同样打开sudo nano /etc/apt/sources.list
  2. 清空原有内容，粘贴下面的源：

     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
     

  3. 保存退出后执行sudo apt update

• 检查网络设置

  • 关闭正在运行的代理或VPN，有时候代理会拦截源请求导致403错误
  • 尝试更换DNS服务器，比如改成谷歌DNS（8.8.8.8）或者Cloudflare DNS（1.1.1.1），避免DNS解析错误导致访问到错误的IP
