Thank you for filing this report! It would appear there might be some local configuration issues here, as the error is due to the postinst failing:

insserv: script mysql: service mysql already provided!
insserv: exiting now!
update-rc.d: error: insserv rejected the script header

Did you do any local modifications to the mysql configuration before performing this upgrade?

[Expired for mysql-5.7 (Ubuntu) because there has been no activity for 60 days.]

I have modify /etc/mysql/mysql.conf.d/mysqld.cnf datadir to /opt, and modify ubuntu apparmor to allow mysql change datadir.
