I like to summarized the grub-pc problem the new point release 10.8 introduced to FAI users.
If you have installed a computer with grub-pc (grub EFI is not affected), FAI installed grub into the MBR of the boot disk(s), but it did not wrote the debconf variable grub-pc/install_devices. After the last point release the grub-pc package complains about this and you have to fix it interactively, so no unattended installations are possible any more. There are two fixes, one for new installation, one how to fix exisiting installation. If you want to install a new machine from scratch with FAI just get the new version of the GRUB_PC/10-setup script. https://raw.githubusercontent.com/faiproject/fai-config/master/scripts/GRUB_PC/10-setup To fix exisiting FAI installation you can use the script grub_debconf.sh from https://fai-project.org/download/misc/ This will detect which device(s) hold a grub MBR and add the list of devices to the debconf variable like this: * grub-pc/install_devices: /dev/disk/by-id/ata-INTEL_SSDSC2CW120A3_CVCV249103KG120BGN You can check if this variable is set by $ debconf-show grub-pc| grep install_devices: Thanks to Carsten for seeing this problem and writing the first version of the script. -- viele Grüße Thomas
