Public bug reported:
On my local network I find that with 18.04 network name lookups using
.local domains no not work unless stimulated by a non-18.04 machine
first. This is observed for ssh, http, https and ping, but probably not
limited to those.
To demonstrate this here is a ping example.
~ $ ping pi.local
ping: pi.local: Name or service not known
~ $ ping pi.local
ping: pi.local: Name or service not known
# At this point head to another machine running 16.04.6 and execute ping
pi.local.
# This is immediately successful. Then head back to the 18.04 machine.
~ $ ping pi.local
