If you just load it without the full /boot/modules path, it's the

16.04 or older.
Just download e.g. 
https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-root.tar.xz
untar somewhere (anywhere, e.g. under the home dir), mount linprocfs, 
linsysfs and devfs under there, chroot into that, and you can use apt 
and whatnot
