Один из моих разработчиков взял на себя задачу обновить один из наших производственных серверов без резервного копирования до OpenSSH 6.2p, этот сервер является и Ubuntu Box работает в EC2, и теперь мы не можем подключиться к SSH, вот выходной журнал из SSH команда.
ssh -i ~/Security/microsites_lamp.pem ubuntu@our.ip.address.here -v

Я убедился, что файл PEM имеет правильные разрешения и сервер работает, но теперь я застрял, можно ли что-нибудь сделать?
