Public bug reported: I am installing Ubuntu 19.10 on my new computer, keeping Windows 10 as dual-boot. I've previously disabled secure-boot and settled legagy boot instead of UEFI. I've manually partitioned my free disk space with LVM and an EXT4 root partition. At the end of the installation process, i get an error when trying to write the boot loader (grub-install). I've tried both whole disk device and first partition (EFI system, already installed with Windows).
While still running from installation usb key, i tried to manually run "sudo grub-install /dev/nvme0n1p1" which gives something like "unable to obtain canonical path to /cow".
