samba - Aug 2018 - "ERROR(runtime): uncaught exception - Unable to load file smb.conf" when doing classicupgrade

Hello,

OS: Ubuntu 18.04.1
Samba: 4.7.6

I use the guide

https://wiki.samba.org/index.php/Migrating_a_Samba_NT4_Domain_to_Samba_AD_(Classic_Upgrade)#Preparations

When trying to execute command

# samba-tool domain classicupgrade --dbdir=/usr/local/samba.LAN/ 
--realm=ad-lan.com --dns-backend=BIND9_DLZ \
   --option="interfaces=lo ens3" --option="bind interfaces
only=yes"
/usr/local/samba.LAN/smb.conf

I get this:

Reading smb.conf
WARNING: The "syslog" option is deprecated
handle_name_resolve_order: WARNING: Ignoring invalid list value 'hosts' 
for parameter 'name resolve order'
ERROR(runtime): uncaught exception - Unable to load file 
/usr/local/samba.LAN/smb.conf
   File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py",
line

     return self.run(*args, **kwargs)
   File "/usr/lib/python2.7/dist-packages/samba/netcmd/domain.py",
line
1584, in run
     s3conf.load(smbconf)

Could someone suggest how to overcome this?

I wish they were all as easy to fix ;-)

Edit the 'name resolve order' line and remove the 's' from the
end of
'hosts', it is just 'host'
