I have not checked where this kernel version is coming from. Maybe it is the "old" ubuntu live system that uses too old packages.

I will look into documentation if there is a a way to update via apt.
Unfortunately the shell is not starting either: "no shell could be found" (from terminal I can start x-terminal-emulator with sudo or after using sudo -i).

Uhh, you need to run apt update or apt-get update before retrieving packages or you'll use out of date package lists.

Also, you didn't mention your host spin, or what guest spin you're trying to rebuild.
(Ubuntu? Lubuntu? Kubuntu?)

I am unable to determine if you're using 16.04 or 18.04 -- that looks like linux-signed-generic-16.04-hwe, not linux-signed-generic, as far as I know, 18.04 was using 4.18?

I advise to use a 'hook' script for customizer to make things as easy as possible.

I use Ubuntu 18.04 (with a Mate desktop, but that should hopefully not matter, I was using the normal gnome-terminal). The official kernel currently is 4.15.0-43 (there is a 4.18 available but I have not found an upgrade package to that kernel as Ubuntu 16 .04 has).

I*m not sure what you are talking about concerning the above problem. At least as I remember the kernel version was hardcoded somewhere. I was up-to-date concerning my package list. Will double check when I'm back home.
