This bug was fixed in the package casper - 1.394.3
---------------
casper (1.394.3) bionic; urgency=medium
* Cherrypick from eoan: Add dependency on finalrd for reliable
live-session shutdown. Casper setup live systems do have layering
violations (/ actually depends on /cdrom) and it appears that
(although masked) the system manages to rip it out, resulting in
filesystem errors preventing completing the shutdown. That's where
pivot to finalrd comes in, to save the day and blast the running
system into oblivion and complete the shutdown. LP: #1840122

Bug description:
Last known good image: Eoan Ubuntu Desktop 20190715
Similar results started to happen with new linux-hwe kernel based on
eoan for 18.04.4 release.
Test Case:
1. Boot eoan desktop to a live session
2. Wait a couple of minutes until snapd settles
3. Reboot the system from the system menu or from the command line
Expected result:
The system reboots
Actual result:
The systems fails to reboot or shutdown and displays some errors about
failing to unmount /cdrom and squashfs errors in a loop.
