por algum motivo, o Docker não está iniciando no meu VPS e recebo o seguinte quando faço "systemctl status docker":
root@vps644072:~# service docker status

Corrigido isso executando "dpkg --configure -a". Isso pareceu também resolver alguns outros problemas que acabei de perceber que estava tendo.

Pode ser um problema no armazenamento de dados, como diz @Shearman reconfigurar pode ser útil, mas em caso de erro mais grave existe sempre a possibilidade de limpar o diretório/var/lib/docker
