ubuntu下容器无法启动报错"failed to start daemon: failed to dial "/run/containerd/containerd.sock": unknown service containerd.services.namespaces.v1.Namespaces: not implemented"如何处理?

答: 使用以下命令重新启动容器
$ sudo systemctl stop containerd
$ sudo systemctl start containerd

启动docker

$ sudo systemctl start docker.service
