Public bug reported:
After upgrading to Ubuntu 16.10 from 16.04, DNS resolution of hosts on
my local network fails.
The hosts line in /etc/nsswitch.conf is:
hosts: files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return]
dns mdns4
If I change it to:
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
I can resolve hosts on my local network. Appending .local to the
hostname also allows DNS resolution since systemd-resolve returns a
different error for that case.
Ex:
systemd-resolve rt-ac66u
rt-ac66u: resolve call failed: All attempts to contact name servers or networks
failed
systemd-resolve rt-ac66u.local
rt-ac66u.local: resolve call failed: No appropriate name servers or networks
for name found
"dig rt-ac66u" returns the correct ip.
