Reportado para mim hoje (dia 15). Erro no browser: 503. Erro no docker ps: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

[Lobz]

$ sudo service docker start Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Erro do docker no journalctl:

Procurei o problema na intternet e encontrei sugestões de rebootar o servidor (https://stackoverflow.com/questions/59752840/docker-socket-failed-with-result-service-start-limit-hit-after-protecting-doc). Seguindo a sugestão de um dos comentários, tambpem conferi o status:

O arquivo de configuração .json contém o seguinte:

        "debug":true
},
{
        "log-level":"debug"
},
{
        "live-restore":true
}

Corrigi o arquivo de configuração e consegui reiniciar o serviço. Novo arquivo de configuração:

{
        "debug":true,
        "log-level":"debug",
        "live-restore":true
}
