【Linux kali 更换yum源】

1、注释原文件的镜像源，添加阿里云镜像源

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

2、apt update，会报错

3、在文件里添加一下内容

[signed-by=/usr/share/keyrings/kali-archive-keyring.gpg]

4、执行这个命令，输入y

curl -fsSL https://archive.kali.org/archive-key.asc | sudo gpg --dearmor -o /usr/share/keyrings/kali-archive-keyring.gpg

5、再次apt update ，成功了
