I removed one repository from my sources.list(rep came from my hoster mirror) where the actual bind9 version came from. And installed the older 1.9.10 version and now it works.
So my problem is solved.
Hello,
my platform is
Debian 9.5 and Plesk Onyx Version 17.8.11
I performed a dist-upgrade yesterday(as my apt-upgrade is saying) so my bind9 server upgraded to 1.9.11.4 After that the bind9 service never came up again.
systemd[1]: Failed to start BIND Domain Name Server.
