Public bug reported:
Running groovy on the desktop, with the systemd packages that migrated
today(/overnight EDT).
# Steps to reproduce:
1) `systemctl restart systemd-resolved.service`
(This is a minimal reproducer, but I first saw this after an apt upgrade
of systemd.)
# Expected behaviour:
DNS continues to work, status looks like this:
Link 2 (enp5s0)
Current Scopes: DNS
DefaultRoute setting: yes
LLMNR setting: yes
MulticastDNS setting: no
DNSOverTLS setting: no
DNSSEC setting: no
DNSSEC supported: no
Current DNS Server: 192.168.1.1
DNS Servers: 192.168.1.1
DNS Domain: ~.
lan
# Actual behaviour:
DNS is unconfigured:
Link 2 (enp5s0)
Current Scopes: none
DefaultRoute setting: no
LLMNR setting: yes
MulticastDNS setting: no
DNSOverTLS setting: no
DNSSEC setting: no
DNSSEC supported: no
# Workaround
Disconnecting and reconnecting my network connection restored DNS
functionality.
