I have just hit this problem on Ubuntu 18.04, and I was able to solve it by
running
root@ubuntu:~# sudo dpkg-reconfigure apparmor
Unlike the previous poster, I am not aware of any sudden powercycles. I
simply attempted to run a docker container. The docker command and
output are below, with PII redacted.
docker run --rm -v /home/[REDACTED]/projects/snap/out/log:/log -v
/home/[REDACTED]/projects/snap/django:/tmslogs -v
/home/[REDACTED]/projects/snap/out/db:/db -v
/home/[REDACTED]/projects/snap/out/media:/media -v
/home/[REDACTED]/projects/snap/out/dumps:/dumps -v
/home/[REDACTED]/projects/snap/config:/config -t -i
[REDACTED].com/tmslogs:latest /bin/bash

I followed the hint in /etc/apparmor.d/tunables/home.d/ubuntu and ran
root@ubuntu:~# sudo dpkg-reconfigure apparmor
This solved the problem.
After this solved the problem, this reminded me that I have modified my
/home directories. After installing Ubuntu 18.04 and creating my
default user account, I logged in and mounted a second drive into
'/home'. Perhaps anyone looking into this issue, or experiencing this
issue could take this clue and run with it.

Problem: Docker containers will not restart due error
/etc/apparmor.d/tunables/home.d/ubuntu at line 7: Found unexpected character: ''
How to recreate problem:
1. initiate unattended upgrades: sudo unattened-upgrades -d
2. Wait until Apparmor is installing...
Installing new version of config file /etc/init.d/apparmor ...
Installing new version of config file /etc/init/apparmor.conf ...
update-rc.d: warning: start and stop actions are no longer supported; falling
back to defaults
Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd
3. Pull the power from the computer to simulate a complete power failure.
4. Plug the system back in and try to restart a docker container using "sudo
docker restart <container-name>
Error upon attempting to restart docker container:
Error response from daemon: Cannot restart container updater-nodejs: AppArmor
