Google 搜了好大一会儿了🤣试了好几个添加 pubkey 的方法，但是都没成功

apt-get update 一下，然后试试安装制定版本的 docker

系统是 debian ？没试过，但是这种东西只看官网就好，按理说官网几条命令直接复制粘贴就可以，

@jackleel 感谢回复
我试了 update，参考了这篇博客 http://www.recall704.com/ops/install-docker-on-debian/尝试安装制定版本的 docker

apt install docker-engine=1.12.6-0~debian-jessie，之后提示是这样的
root@ip-172-2*-**-133:~# apt install docker-engine=1.12.6-0~debian-jessie

是的，系统是 debian10.8，按照官网的命令和各种“一键安装 docker”都试过了，每次都会提示 no punkey

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

这是官方的脚本，出错的话估计你之前折腾把系统环境搞坏了，如果方便可以重置下系统

@lysS 感谢大佬！！！重置系统果然有效！！！
祝大佬早日暴富！！！
