То, что могло бы вызвать “версию 'KERNEL_VERSION', имеет неверный синтаксис: номер версии не запускается с цифры” во время обновления-initramfs-u

Когда я работаю sudo update-initramfs -u Я получаю вывод ошибок

dpkg: warning: version 'KERNEL_VERSION' has bad syntax: version number does not start with digit
update-initramfs: Generating /boot/initrd.img-KERNEL_VERSION
dpkg: warning: version 'KERNEL_VERSION' has bad syntax: version number does not start with digit

Я подозреваю переменную, которая accidentially интерпретируется как литерал, таким образом, я работал

• sudo grep -r 'KERNEL_VERSION' /boot/ и sudo grep -r 'KERNEL_VERSION' /lib/ без результата и
• sudo grep -r 'KERNEL_VERSION' /usr/ возвраты слишком много результатов для исследования.

Я использую Ubuntu 15.04 amd64 с Linux 4.0.0.

sudo update-initramfs -u -v производит вывод
