[Samba] Samba Won't start after upgrading Operating system

[Robert Steinmetz]

I ungraded my Linux Operating system from Ubuntu 16.04 LTS to 8.04 LTS

Samba will not start after an upgrade to 18.04. My samba is running as 
an NT style member server server with smbd nmbd and winbindd all 
running. None of them will start.

It worked this morning.

This morning it was running Version 4.3.11-Ubuntu

This afternoon after the upgrade it's Version 4.7.6-Ubuntu

The logs in /var/spool/samba are empty.

Job for smbd.service failed because the control process exited with 
error code.
See "systemctl status smbd.service" and "journalctl -xe" for details.

The information on all three processes is virtually identical.

testparm gives a few warnings but it's been doing that for a while with 
no apparent problem See below.

I've found a number of posts with similar problems but none seem 
directly on point.
