ALERT! /dev/mapper/ubuntu–vg-root does not exist. Dropping to a shell!

As of last night my Ubuntu 19.04 laptop won’t boot into its latest kernel. In the hours beforehand I had completed an apt-get upgrade and autoremove. The system continued along perfectly fine. After a reboot however, I reach an (intramfs) shell prompt.

Typing exit at this prompt I am then given the alert message:

ALERT! /dev/mapper/ubuntu–vg-root does not exist. Dropping to a shell!

I have discovered that I can successfully boot into an older kernel through the grub menu.

Latest installed kernel: 5.0.0-25-generic (not working

Backup kernel: 5.0.0-21-generic (working)

My system runs an LVM partitioned drive.

I found an old thread with the same symptoms that advised running ls /dev/mapper at the intramfs shell. All that returns is /dev/mapper/control

Any help would be greatly appreciated. Also, if there’s more info required please just let me know.

TIA

Every startup i need to manually run fsck /dev/mapper/ubuntu–vg-root

Hi every day when I start my ubuntu 18.04, then it’s not starting and gives a below error.

(initramfs) exit /dev/mapper/ubuntu--vg-root contains a file system with errors, check forced. Inodes that were part of a corrupted orphan linked list found.  /dev/mapper/ubuntu-vg-root: UNEXPECTED INCONSISTENCY; Run fsck MANUALLY.     (i.e., without -a or -p options)  fsck exited with status code 4. The root file system on /dev/mapper/ubuntu--vg-root requires manual fsck 

When I run command fsck /dev/mapper/ubuntu--vg-root

it solves error but again the next day when I start up my system it shows same error again and needs to run the command again.
