I've got unattended upgrades configured on my system. Every so often emails come in that a reboot is required. Yesterday after I rebooted my system to complete an upgrade, only to find that mysql-server had been removed from my system. /etc/init.d/mysql did still exist, but the mysqld and mysqld_secure executables were nowhere to be found. I've had this before with a different package.

How can I figure out why this happened, and how to prevent this in the future?

The first email that said I needed to reboot (5th of Oct):

Unattended upgrade returned: True

Warning: A reboot is required to complete this upgrade.
