Confirmed from comment #11 by mbdev Adding a global_filter to line 151 just after the default section corrected the problem.
Before adding the filter to /etc/lvm/lvm.conf I was getting this: ``` Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ... /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found Found linux image: /boot/vmlinuz-5.3.0-46-lowlatency ``` After adding the comment, it seems to be corrected: ``` $ sudo update-grub Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ...
