Thanks for filing this bug in Ubuntu.
It looks like mysql was shutdown when the upgrade script kicked in:
Setting up mysql-server-5.7 (5.7.23-0ubuntu0.16.04.1) ...
insserv: warning: script 'S03cinder-setup-backing-file' missing LSB tags and

Upgrade process encountered error and will not continue.
mysql_upgrade failed with exit status 11
dpkg: error processing package mysql-server-5.7 (--configure):
subprocess installed post-installation script returned error exit status 1
The mysql logs just show a graceful shutdown:

There are also some apparmor denied messages:

Could you please try the following:
sudo systemctl restart mysql
sudo systemctl status mysql
And then:
sudo apt update
sudo apt -f install
And keep an eye in the output of "dmesg -w" while doing that, to see if
new apparmor DENIED messages appear.
Thanks!
