Ubuntu fails and requires a hard reboot. This appears to be due to the file system becoming readonly.

Ubuntu fails and requires a hard reboot. This appears to be due to the file system becoming readonly.

This has happened many times over the past few months. Tonight, these were the programs being used when the system died.
    1. Gnome Terminal 3.38.1
    2. Evolution 3.40.4-1
    3. Gnome Files 40.2
    4. Firefox Browser 95.0.2 (64-bit)
    5. Chromium Browser Version 96.0.4664.110 (Official Build) snap (64-bit)
    6. Rythmbox 3.4.4
    7. Code42 Crashplan 8.8.1 running in the background, may or may not have been performing a backup
    8. LibreOffice: Writer and Calc
         Version: 7.2.3.2 / LibreOffice Community
         Build ID: 20(Build:2)
         CPU threads: 8; OS: Linux 5.13; UI render: default; VCL: gtk3
         Locale: en-US (en_US.UTF-8); UI: en-US
         Ubuntu package version: 1:7.2.3-0ubuntu0.21.10.1
         Calc: threaded

When I attempt to shutdown or reboot, the screen changes to a non-graphical display with unending errors about the file system.

My system is up-to-date and I’m using Wayland.

Visiting https://errors.ubuntu.com/user/ID I get “No errors have been reported from this system”.

/etc/default/apport does have “enabled=1” and it’s not commented out.
