Добрый день!
не хочу создавать новую тему. Не могу залогиниться в систему ни по SSH, ни по консоли напрямую. могу кое-как подключиться через Webmin
система Ubuntu server 14.04.4 LTS, используется как файл-сервер, подключен к домену с помощью Samba, Winbind, kerberos.
возникла проблема после обновления, в консоли при попытке залогиниться на доли секунды возникает ошибка(успел сфотографировать)
Error in `/bin/login`: double free or corruption (fasttop): 0x0000000
привожу лог auth.log с включенным дебагом

в проблеме разобрался, на зарубежном форуме нашел.
был кривой пакет libpam-smbpass, после удаления которого ssh заработал
