Package: cloud.debian.org Ohai,
when trying to update a VM based on the debian/buster64 box from 10.4 to 10.8, grub-pc can't be upgraded non-interactively because it doesn't know which devices to install GRUB to (grub-pc/install_devices debconf question is empty) and that's a fatal error for GRUB. In our environment I "fixed" that by setting grub-pc/install_devices_empty to "true" (AKA "it's okay to not install GRUB to any devices during upgrade"), as we don't exactly care about the box being rebootable. However I think this should be ultimately be fixed inside the box in a nicer way? Maybe a first-boot script that checks what device the system booted of (sda, vda, whatever) and sets grub-pc/install_devices to that device? Thanks a ton for maintaing those boxes! Evgeni
