ah you're using the libvirt box these boxes are built with vmdebootstrap which is unmaintained:/ there is work in progress to replace vmdebootstrap with fai-diskimage at https://salsa.debian.org/cloud-team/debian-vagrant-images which should fix this. Until then I am afraid we have to live with manually setting echo 'grub-pc grub-pc/install_devices multiselect /dev/vda' | sudo debconf-set-selections before doing an apt upgrade
