Hello Andrew,
Thank you for your reply (very much appreciated).

I have installed the most recent version I could find at:
https://github.com/rthalley/dnspython
The script samba_upgradedns returns the following error:
Error parsing DNS data from '/opt/samba/private/dns/TH01.INET.zone' (The
DNS zone has no SOA RR at its origin.)
This could mean that I should add a Start of Authority Resource Record at
the top of the TH01.INET.zone file to make it work/acceptable? I am
considering to create a backup of this file and try again with a SOA RR.
I am only a little bit worried about the second exception.
Please note: I just did upgrade to Samba 4.4.3 (as I do want to change over
to Samba's internal DNS).
The returned error is:
Traceback (most recent call last):
File "./samba_upgradedns", line 317, in <module>
ncname = msg[0]['nCName'][0]
KeyError: 'No such element'

I will file a bug as soon as possible.

Does this mean that the script would end without issues when I add a SOA RR
to the zone file combined with a fix regarding to the second exception? Note:
I just did upgrade to Samba 4.4.3.
Please find my console output below.
