kaili更新国内源，“没有数字签名”错误

1.更新国内源，

打开源文件：（记得把注释去掉#）

vim /etc/apt/sources.list

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

2.然后更新源就ok

sudo apt-get update

但是我做的时候出现错误

 其实从官网下载安装签名就可以了

wget archive.kali.org/archive-key.asc
apt-key add archive-key.asc
