Boa tarde, De acordo com o log a porta já está em uso, provavelmente o sshd já está em execução, se sua intenção é "debugar", pare o serviço com, sudo service ssh stop Logo após executa o sshd manualmente, /usr/sbin/sshd -d -D Se executar, tenta efetuar o login, ssh localhost -p2928 E envia os respectivos logs pra gente. Até mais.
