update-grub не работает - носитель не найден

Я запускаю Ubuntu 20.04 LTS с LVM и UEFI на Thinkpad T480.

Всякий раз, когда я бегу sudo update-grub, Я получаю такой результат:

Adding boot menu entry for UEFI Firmware Settings
done

Мои изменения не вступают в силу после выполнения команды.

У меня нет тома под названием /dev/sdb... Я не понимаю, зачем ему это искать.

Как я могу исправить эту проблему?

Заранее спасибо.

Решение из этого комментария к отчету об ошибке на панели запуска:

Добавить global_filter = [ "r|/dev/sda|", "r|/dev/sdb|" ] в файл /etc/lvm/lvm.conf:

        143         # Example
 144         # Accept every block device:
 145         # filter = [ "a|.*|" ]
 146         # Reject the cdrom drive:
 147         # filter = [ "r|/dev/cdrom|" ]
 148         # Work with just loopback devices, e.g. for testing:
 149         # filter = [ "a|loop|", "r|.*|" ]
 150         # Accept all loop devices and ide drives except hdc:
 151         # filter = [ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]
 152         # Use anchors to be very specific:
 153         # filter = [ "a|^/dev/hda8$|", "r|.*|" ]
 154         # 
 155         # This configuration option has an automatic default value.
 156         # filter = [ "a|.*|" ]
 157         global_filter = [ "r|/dev/sda|", "r|/dev/sdb|" ]

Бегать sudo update-grub перед фильтром:
