дружественное восстановление при запуске apt (обновление, dist-upgrade или автоматическое удаление)

При запуске apt, upgrade, dist-upgrade или autoremove я получаю сообщение об ошибке friendly-recovery и grub. Я искал вокруг, но не могу найти решение. Кажется, для обновления / установки других пакетов нормально.

Я включил команду, выходные данные и соответствующие файлы из того, что я понимаю. Если вам нужна дополнительная информация, пожалуйста, дайте мне знать.

Надеюсь, что кто-то может помочь!
