my laptop is failing to boot every time, so when I turn it off to go to the GRUB boot loader for help I'm seeing what looks like two images which are:

4.0.15-42 generic and recovery 4.0.15-20 generic and recovery

try as I might, 42 will not boot but 20 does. Is there any way that I am able to remove 42 so that my device will boot without me having to intervene with GRUB every time?

Thanks,

AJ

I observed the same when upgrading from 4.15.0-39 to 4.15.0-42 on my Ubuntu 18.04.1 NAS (x86_64):

Failed to execute /init (error -2) second line: Kernel panic - not syncing: no working init found.

So apparently the init is broken. My solution was to remove 4.15.0-42 

sudo apt remove linux-image-4.15.0-42
sudo apt autoremove

and, thus, automatically go back to 4.15.0-39 which works fine. The autoremove removed amd64-microcode, intel-microcode iucode-tool and thermald which appear to be needed by -42 only.

(In order to be able to do the above, boot from a live CD/DVD/USB and chroot to the Ubuntu installation)
