Package: grub2-common Version: 2.02~beta3-3 Severity: normal File: /usr/sbin/grub-install
Hi! grub-install does not check the return value of efibootmgr: | grub-install: info: Registering with EFI: distributor = `debian', path = `\EFI\debian\grubx64.efi', ESP at hostdisk//dev/sda,gpt1. | grub-install: info: executing efibootmgr --version </dev/null >/dev/null. | grub-install: info: executing modprobe -q efivars. | grub-install: info: executing efibootmgr -c -d /dev/sda -p 1 -w -L debian -l \EFI\debian\grubx64.efi. | Could not prepare Boot variable: No space left on device | Installation finished. No error reported. Despite efibootmgr failing and returning an eror code (5) grub-install claims installation was successful. This resulted into an unbootable system. See also #845023 for an example. grub-install should check the return code of efibootmgr, report it to the user, and (idealy) suggest a strategy to workaround this firmware bug. Daniel
