You need to have efivarfs mounted, which Debian/jessie and systemd 
should do by default (it certainly does, at least when booted in UEFI
mode - you probably won't have access to it in BIOS CSM mode):

$ grep efivarfs /proc/mounts 
efivarfs /sys/firmware/efi/efivars efivarfs rw,nosuid,nodev,noexec,relatime 0 0

If it isn't for some weird reason, you'll have to mount it by hand.

# mount -t efivarfs -o rw,nosuid,nodev,noexec,relatime efivarfs /sys/firmware/efi/efivars
