Então eu instalei o openSSH-server no meu ubuntu 16.10 com sudo apt-get install openssh-server e ele funcionou MAS quando eu digito sudo service ssh start ele diz
Job for ssh.service failed because the control process exited with error code. see systemctl status ssh.service and journalctl -xe for details.
Eu digito systemctl status ssh.service e diz o seguinte
'"ssh.service - OpenBSD Secure Shell Server

Alguma idéia de como corrigir isso? Eu pesquisei algumas horas mas não encontrei nada de útil. thx de antemão.
