应该是镜像源的问题吧，没找到对应的包。
换源后手动执行一下 apt-get -y -qq install docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-ce-rootless-extras docker-buildx-plugin docker-model-plugin 验证

用这个方法安装试试吧，这个报错就是阿里的源上面没有plugin这个包

使用 https://www.cnblogs.com/surplus/p/11367556.html 方法装上了docker  又报
failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to register "bridge" driver: failed to create NAT chain DOCKER: iptables failed: iptables --wait -t nat -N DOCKER: iptables v1.8.2 (nf_tables):  CHAIN_ADD failed (No such file or directory): chain PREROUTING
我也是服了,算懒得重装系统,麻烦官方把 教程写清楚一点好吗,至少把能安装镜像版本写一下

你这个是什么时候的文档？怎么感觉是以前的。
还有猫1的话去安装docker.io，docker-ce是用不了的。
