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.
