ProxySQL 1.3.7-1.1.xenial breaks automatic startup


I just install the upgrade to version 1.3.7-1.1.xenial on my Ubuntu machines. Now the service doesn’t start automatically anymore. I tried to fix this by enabling, disabling and removing, readding it with update-rc.d but it didn’t help. Also the systemd service doesn’t work. To test it I removed the sysvinit scripts and enabled the proxysql service with systemctl.
As a temporary fix I’ve added a start command to my rc.local.
What’s the problem here?
