Public bug reported: I have installed all updates to my system recently. Then I tried to connect to this system from my LAN and was unable to connect. So I tried to restart ssh service:
sudo service ssh restart Job for ssh.service failed because the control process exited with error code. See "systemctl status ssh.service" and "journalctl -xe" for details. фев 04 23:22:00 norbert-vaio systemd[1]: Failed to start OpenBSD Secure Shell server. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Unit entered failed state. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Failed with result 'exit-code'. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Service hold-off time over, scheduling restart. фев 04 23:22:00 norbert-vaio systemd[1]: Stopped OpenBSD Secure Shell server. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Start request repeated too quickly. фев 04 23:22:00 norbert-vaio systemd[1]: Failed to start OpenBSD Secure Shell server. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Unit entered failed state. фев 04 23:22:00 norbert-vaio systemd[1]: ssh.service: Failed with result 'start-limit-hit'.
