For me I can give some context: - DELL XPS 9370 - Installed 18.04, dual boot, part of which I think meant that I needed secure boot (may be wrong) - Attempted to upgrade Kernel to fix some bluetooth issues (known bugs) using UKUU - Kernel install went OK, grub updated, but then on reboot the system complains that the kernel is not signed - Attempted upgrade to 18.10, failed on same issue to new kernel not being signed - But rebooted and checked kernel and it had updated OK to 4.18... Thanks all I know... hope it helps.
