Bug Description

Context: fresh install of zesty via

debootstrap --include=nano,dbus,iputils-ping,iproute2 zesty zesty1 http://fr.archive.ubuntu.com/ubuntu

ran via asystemd-nspawn with a static IP

1. Upon first connexion, a ping fails:

root@zesty1:~# ping google.com
ping: google.com: Temporary failure in name resolution

2. The content of /etc/resolv.conf:

root@zesty1:~# cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

3. When running systemd-resolve --status:

root@zesty1:~# systemd-resolve --status
Global
         DNS Servers: 8.8.8.8
                      8.8.4.4
                      2001:4860:4860::8888
                      2001:4860:4860::8844
          DNSSEC NTA: 10.in-addr.arpa
                      16.172.in-addr.arpa
                      168.192.in-addr.arpa
(...)

4. After running this command the resolution is miraculously restored:

root@zesty1:~# ping google.com
PING google.com (172.217.22.142) 56(84) bytes of data.
64 bytes from 172.217.22.142 (172.217.22.142): icmp_seq=1 ttl=53 time=2.62 ms
64 bytes from 172.217.22.142 (172.217.22.142): icmp_seq=2 ttl=53 time=1.93 ms
