You originally posted you are using Ubuntu 18.04, was this a typo:

Samba Version 4.6.7

Should it have been 4.7.6 ?

You shouldn't be getting a panic, is anything getting in the way ?
I would stop Aparmor and any firewall, double check you have all the
required packages installed.
You mentioned that you started this as a migration, but from what ?
Did you run the classicupgrade tool and if so how ?
Did you provision a new domain and if so how ?
Did you do something else ??
