Недостаточно памяти в / boot во время обновления ядра - повреждено ядро

Я запустил apt-get upgrade для обновления моего ядра вчера (ubuntu 15.04) и / boot не хватило памяти (обычно, если не хватает места, это мешает запуску задачи обновления)

Я случайно удалил активное ядро ​​побуждает меня выполнить эти шаги здесь - Как восстановить систему после случайного удаления всех ядер?

Я застрял на шаге 13, так как предыдущая ошибка памяти мешает мне установить текущее ядро ​​или обновление оставшегося ядра.

Обновление выдает следующую ошибку

Я также пытался очистить и установить свежие, без кубиков из-за той же ошибки

Я полагаю, что это оправдывает свой вопрос как это вопрос dpkg, а не тот, который напрямую связан с вопросом выше
