Thanks Thomas for the pointer to #982182. The bug on the Vagrant box is similar but the root cause is different. On the latest buster box: vagrant ssh -- sudo debconf-show grub-pc | grep grub-pc/install_devices: * grub-pc/install_devices: /dev/vda This is because the box is built with packer which uses virtio-blk from qemy by default and create such devices. So for the vagrant side of this, at least for buster we should switch the default disk driver to virtio-scsi, which creates during the install a /dev/sda debconf entry, which is the same device name grub sees on VirtualBox and its sata controller.
