有什么建议吗

根据docker官方安装指南，在ubuntu上安装docker ce有三种方法：

使用存储库安装

安装DOCKER CE

从软件包中安装

建议：选择second轻松在Ubuntu上安装docker ce，只需确保安装最新的稳定版本而不是edge，直到您对edge有特定要求开始之前不要忘记阅读官方安装指南。

sudo nano/etc/docker/daemon.json 加上这个,， { “存储驱动程序”：“overlay2” } 编辑这个， sudo nano/etc/default/docker 加上这个。DOCKER_OPTS=“-s覆盖” 然后重新加载sudo systemctl守护进程

sudo systemctl重新启动docker，它会工作。

只是好奇而已。你从哪儿弄来的？
