I upgraded my OS from 16.04 to 18.04 yesterday. While upgrading for 6 packages (namely grub-efi-amd64, gdm3, grub-efi-amd64-signed, cups-pk-helper, ubuntu-desktop, gnome-initial-setup ) installation failed but process said upgrading will continue. So I assumed that I'll be able to update them after reboot. System rebooted fine after that but whenever I try install any new packages I get the following error message.

I realise that it's because of these 6 broken packages and I've tried solutions mentioned here, here and here (installed mokutil, but no difference). I've also tried tried to re-install these packages individually, but it didn't work. Another solution mentioned here suggested me to remove these packages from status file in dpkg, but since two of them were related grub I didn't want to mess around with that.
Could anyone please help me out to figure these issues out? Thanks in advance.
Edit: This link says removing grub entirely and re-installing it. Is it safe to do this? Since this is my work laptop I really don't want to mess around too much.
Edit 2: FYI, I've installed Ubuntu in EFI boot

Edit 3: I've tried efibootmgr and got this output, not sure why. I have no problem in booting my system.

Edit 4: Adding some more info, in case it helps for diagnosis. Looks like grub-efi-amd64 is partially configured and it's signed is unpacked. My doubt is how am I able to boot my system when this is only partially configured. And why can't I finish this installation?
