Ошибка установки postgres на Ubuntu 14.04 [в ожидании]

Я уже некоторое время безуспешно пытаюсь установить postgres. Мне пришлось выключить сервер Digital Ocean Ubuntu 14.04, чтобы переключить его ядро, и после перезагрузки что-то пошло не так с пакетом postgres. После установки я продолжаю выводить эту ошибку и не могу запустить любую версию postgres, кроме 9.3

invoke-rc.d: initscript postgresql, action "start" failed
