Debian - DNS -> Unit dbus-org.freedesktop.resolve1.service not found (DNS stopped working)

This problem is related to the network-manager and systemd-resolved.service.

After reading the the manjaro forums and the arch wiki

You have 2 options

configure network-manager to not use systemd-resolved.service

vim /etc/NetworkManager/conf.d/no-systemd-resolved.conf

With this content:

[main]
systemd-resolved=false

Activate and use systemd-resolved.service

check if it is running and enabled

systemctl status systemd-resolved.service
● systemd-resolved.service - Network Name Resolution
  Loaded: loaded (/usr/lib/systemd/system/systemd-resolved.service; disabled; vendor preset: enabled)

          https://www.freedesktop.org/wiki/Software/systemd/writing-resolver-clients

Enable and start it.

systemctl enable systemd-resolved.service

That solved the errors from coming up in the logs.
