dkpg error on Linux Kernel version syntax

[anonimou0]

I'm trying to install wireguard on the Banana PI R2 running Ubuntu 16.04, latest image.

However, on the installation, I'm getting an error that reads:

dpkg: warning: version '*-*' has bad syntax: version number does not start with digit
It is likely that 4.4.70-BPI-R2-Kernel belongs to a chroot's host
Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.

There is an workaround, not Banana PI related, here: openzfs/zfs#1260

However, as the kernels are not provided by default repositories, I can't install this generic kernel.

Any help on this is appreciate. Thanks
