I just ran into Robie's problem at my site. I have a 16.04 server setup in a VM running mysql 5.7.17 Community Edition.

About two weeks ago, we started having the mysqld throw apparmor errors and die every day at a random time.

What appears to be happening is the daily apt update is trying to update mysql.

The random time is a consequence of it being run by the systemd timer for cron.daily.

For some reason, part of that update involves a configuration change to mysqld.

/etc$ sudo apt-get upgrade --simulate | grep -i sql
Conf mysql-server-5.7 (5.7.17-0ubuntu0.16.04.1 Ubuntu:16.04/xenial-updates, Ubuntu:16.04/xenial-security [amd64])

At that time, either during shutdown or reload, mysqld is trying to check the status of itself (or the previous instance?) and is being rejected by apparmor:
