No, do you have a line in /etc/Network-Manager/Network-Manager.conf
with 'dnsmasq' in it ?
If so, comment it out and restart Network-Manager

What is in /etc/hosts and /etc/resolv.conf ?

You could be right, is apparmor running ?
I use Devuan

It is correct on Devuan, so should be correct on debian, but check who
runs DHCP on your system.

I will send you a script to replace the /etc/dhcp/bin/dhcp-dyndns.sh.
It is the same as the one on the wikipage, but it will output
information to a text file in /tmp: /tmp/Update.txt
It also has '-d' hardcoded.

If you can try this script and then send me /tmp/Update.txt and
anything relevant from /var/log/syslog, I will see if I can work out
what is going wrong.
