我最近在安装 raspbian 时遇到了问题。可能是一些升级搞砸了我的 SSD 启动。解决后，我注意到 docker.service 拒绝启动。在服务的日志上它说

据报道
pi@raspberrypi:~ $ docker start homeassistant
Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/7c4732337e167e0f8178b8667bddc0393c2c1e4f7ffba5d68fe57379cc1de7c0/merged: no such file or directory
Error: failed to start containers: homeassistant
这是 docker info 的结果
