Как решить проблему pam_unix(sshd:auth): authentication failure?

Question

Добрый день!

После несколькх дней работы на Vps докер благополучно упал:

sudo service docker start

A dependency job for docker.service failed. See 'journalctl -xe' for details.


journalctl -xe

В чем может быть причина?

Может ли быть из за того, что у меня нет файла: /var/run/docker.sock

Раннее для успешного запуска проделывал следующие действия:

sudo addgroup --system docker;
sudo adduser $USER docker;
newgrp docker;
sudo service docker restart;
sudo reboot NOW

На этот раз не помогает.

Есть еще такой лог:

journalctl -f
