update-grub not working -- No medium found
Я запускаю Ubuntu 20.04 LTS с LVM и UEFI на Thinkpad T480.
Всякий раз, когда я запускаю sudo update-grub, я получаю следующий результат:
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'

Adding boot menu entry for UEFI Firmware Settings
done
Мои изменения, похоже, не вступают в силу после выполнения команды.
У меня нет тома с именем /dev/sdb... Я не понимаю, почему он должен его искать.
Как я могу решить эту проблему?
Заранее спасибо.

Решение из этого комментария на панели запуска отчета об ошибке:
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|" ]
