Не обновляются пакеты Ubuntu из-за ошибки grub-efi

Использую VDS с установленной Ubuntu 20.04. Не удаётся обновить пакеты apt update и apt upgrade. Получаю ошибку из-за grub-efi. Вот то, что выводит консоль:

Можно было бы переустановить ОС. Но потом нужно будет заново устанавливать и настраивать окружение. Пробовал удалить и заново установить, но консоль выдаёт туже самую ошибку.

Можно ли исправить ошибку? И в чём может быть причина возникновения?
