I noticed in synaptic that the package linux-signed-image-4.13.0-39-generic stated : not configured.I am unable to update to .39 , I get Software Index is broken box which says to run sudo apt-get install -f, but as you can see I have done that to no avail. What can I do?
When I try to reinstall linux-image-4.13.0-39-generic:amd64 i get an error E:Internal Error, No File name for linux-image-4.13.0-39-generic, I am trying to install all the packages that were going to be upgraded.

Update I somehow managed to install all the .39 packages yet my uname -a states i am on 4.13.0-38-generic, what can I do to switch it to .39
Do I need to purge all those linux-image-4.13.0-39-generic packages and reinstall from fresh? Would that help any, but anytime I try to manage the image-4.13.0-39 i get that E:Internal Error.
These are the files that need to be upgraded / installed

Maybe using dpkg -i on those .deb files will work(?).

This is the part of syslog that was a clue

I had a lot of help solving this issue with someone who is much more skilled with linux OS than me,I will post how I did it here in case anyone else finds themselves in this situation; a halfway installed kernel, thank god I was able to boot into it. First I checked my

Quote:

/etc/default/grub

-> "quiet splash" and I noticed that it was missing a little line inside

Quote:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=force"

I recalled there used to be a second option in there "quiet splash", so instead of doing the nano way, I decided to purge grub-common and remove the 5 other dependencies ( I made sure to write each one of them down so I could reinstall later on.
And here is how this went down, I was on the machine, not via ssh, too many variables can go wrong doing such work with ssh

Code:

dpkg --get-selections | grep grub - this allowed me to see all the dependencies
   apt-get purge grub2-common - this removed my grub2
   apt-get install grub2-common - this reinstalled my grub2
   update-grub - always run this after any grub2 work
   apt-get install shim - dependency
   apt-get install grub-efi-amd64-bin - dependency
   apt-get install grub-efi-amd64- dependency
   apt-get install grub-efi-amd64-signed- dependency
   apt-get install grub2-themes-ubuntu-mate- dependency
   dpkg --configure -a
   update -grub -to finish off the process

I later checked my /etc/default/grub and as I have suspected that option was there

Code:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
GRUB_CMDLINE_LINUX=""

I was now able to reinstall the latest kernel and no more errors. By the way guys, what option can I input here /etc/default/grub during the bootup phase which would allow me to pick which kernel or kernel recovery I can choose, this would come in very handy, as it stands now, it all goes by so fast I can't even get into the grub options by holding down the shift button
