Thanks!
My file looks like this:

Unattended-Upgrade::Origins-Pattern {
        "o=*";
};
Unattended-Upgrade::Automatic-Reboot "false";
Unattended-Upgrade::Mail "root";

I appended "Unattended-Upgrade::Remove-Unused-Dependencies "false";" to 
the end of the file. Let's hope that this does not happend again :)

Thanks for the tip!
