Kernel panic trying to boot 4.4.0-146-generic after apt upgrade on 16.04.6

Question

I can't boot the 4.4.0-146-generic kernel because of a kernel panic. I'm running 16.04.6 on an Intel Core i7-7500U CPU @ 2.70GHz × 4. See image below:

You can try booting the previous kernel version on Grub's Advanced Options submenu. Let us know if that works ok. — WinEunuuchs2Unix, May 13 '19 at 01:18
@WinEunuuchs2Unix, yes that worked fine and this solution already solve it. — luilver, May 14 '19 at 19:30

Try to boot your Linux from the live CD/DVD, into the recovery mode prompt, then check your root fs, e.g.

fsck /dev/your_drive

^{Note: Add -y to fix any errors automatically.}

Or:

chroot /mnt/sysimage
fsck -y /dev/mapper/dom0_root

The usual cause can be:

Broken grub config.
Root partition not flagged as bootable.
Bad installation (initramfs lacks or uses modules of another kernel version).
Bad RAM, try replacing. See: Random Kernel Panic on boot - not syncing.

You can try to fix your Grub record by:

Mount your LXLE /boot partition (for instance at /mnt/boot).
Install Grub bootloader by: grub-install --boot-directory=/mnt/boot /dev/sdX
Then run: grub-mkconfig -o /mnt/boot/grub/grub.cfg.
Optionally, if it fails to detect your other system, edit grub.cfg file manually.
