Yes, it seems that the kernel cannot extract the initrd, because (very
weird!) for some reason the 4.7 kernel you are trying to use lacks
builtin support to extract gzip (???). This looks pretty weird, but
might explain the problem.

You should try to compress the initramfs with either bz2 or xz. It
seems that xz-utils is not installed in your system, so you should
first

apt-get install xz-utils

and then recreate the initramfs again. If xz is available, initramfs
should try to compress the initramfs with xz. Hopefully, the 4.7
kernel you are trying to install will have at least xz support...
