这是我的第一个问题，所以我希望我问对了。我在VirtualBox VM中运行docker（来宾操作系统是Ubuntu 18.04）
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Codename: bionic
前几天，我发生了“计划外重启”（即电源故障），该重启一定损坏了某些文件，因为docker服务将不再启动。我尝试修复和修复docker，最终按照https://askubuntu.com/questions/935569/how-to-completely-uninstall-docker上的说明卸载了docker。
之后，我按照https://docs.docker.com/engine/install/ubuntu/上的标准说明从头开始重新安装了docker。
在安装的最后一步，我收到一些错误，请参见此处：

我怀疑在计划外的重启过程中，containerd.io发生了一些变化，但是当我运行docker install时，它说containerd.io已经是最新版本，因此不会重新安装。
如果我尝试systemctl start docker，它只会返回Job for docker.service canceled.。但实际上我可以运行sudo dockerd，泊坞窗将启动。我只是无法让它作为服务启动。
有人有什么建议吗？我已经搜索了这些错误，并发现了一些稍微相似的结果，但情况与我不完全相同。我只需要重新安装containerd.io吗？如果是这样，由于系统认为它已经正确安装，该怎么办？
