Trying to get Virtualmin GPL to upgrade but running in to issues with Bind9?
If you get some garbage about AppArmor during the bind9 update, do this:
cd /etc/apparmor aa-complain usr.sbin.named
Might need to do it as the daemon user as shown here:
Getting "named clients-per-query decreased to" in the logs?
Crank up logging to see what is up and check syslog:
Pop that up again to dispense with that logging.
