Agree with the comment and this particular update process is likely acting as expected since an unsigned kernel was found. However, just to set the context right - I didn't install the unsigned kernel. I rolled back kernel 4.15-0-177 to work around Bug #1973482, using apt remove and it automatically installed the unsigned version instead.
