We're recently discussed changing 'client max protocol = SMB3' so
that smbclient and other utilities work against servers
with disabled SMB1 by default.

We hope to get this into 4.7, but there's only about 3 weeks
left to make this change (until 4.7.0rc1 is branched from master),
so it's not sure if such a change will make it into 4.7.0 (released
in September).

I guess changing the defaults for the min protocol values will
take a lot longer. The earliest would be 4.8.0 (early March 2018),
but I'm not sure we'll change it by then.

But you could also have custom patch in ubuntu 18.04 that
raise the default values.
