Обновление до 16.04 с 14.04 завершилось неудачно с неразрешимой проблемой при расчете обновления

Я получаю «При вычислении апгрейда возникла неразрешимая проблема». Когда я пытаюсь перейти с 14.04 на 16.04, читая другие вопросы по этому поводу, я пытался проверить файл журнала /var/log/dist-upgrade/main.log, но я не понимаю, что пакет ведьмы является причиной проблемы.
