Невозможно установить новый пакет или обновить существующие на 18.04 LTS
Я не могу установить новые пакеты или обновить существующие пакеты до Linux-image-4.15.0-32-generic, Linux-image-4.15.0-34-generic и Linux-image-4.15.0-38-generic. Скриншот сообщения об ошибке
Я пробовал решения, представленные здесь, но это не решает проблему: у меня проблема с менеджером пакетов на 18.04 LTS
Есть ли способ, как я могу решить эту проблему без форматирования моего ПК? Спасибо
