While I'm pretty sure this "bug" is upstream, I thought better check here to see if anyone else is experiencing this.
systemd[1]: /etc/systemd/system/systemd-resolved.service.d/override.conf:3: Unknown section 'Resolve'. Ignoring.
However, you can check from /etc/systemd/resolved.conf
that the section is indeed called Resolve
[Resolve]
#DNS=
#FallbackDNS=`
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#Cache=yes
#DNSStubListener=yes
for completion sake, here's the contents of my override.conf
file contained in /etc/systemd/system/systemd-resolved.service.d/override.conf
[Service]
Environment=SYSTEMD_LOG_LEVEL=debug
[Resolve]
DNS=1.0.0.1 1.1.1.1
# FallbackDNS=8.8.4.4 8.8.8.8
DNSSEC=allow-downgrade
