wbinfo -u didn't work

I manually downgraded to 4.16.2 now and hopefully got all needed packages.

Yes, I quickly browsed the existing threads before writing this.

smb.conf of that DC:

[global]
	workgroup = ARBEITSGRUPPE
	realm = arbeitsgruppe.my.tld
	netbios name = ADC2
	server role = active directory domain controller
	idmap_ldb:use rfc2307 = yes
     	dns forwarder = 10.0.0.254 9.9.9.9
	winbind offline logon = yes
	log level = 1

	# disable printing completely, when set empty no error log messages.
         load printers = no
         printing = bsd
         printcap name = /dev/null
         disable spoolss = yes

         # disable usershares creating, when set empty no error log 
messages.
         usershare path 
[netlogon]
	path = /var/lib/samba/sysvol/arbeitsgruppe.my.tld/scripts
	read only = No

[sysvol]
	path = /var/lib/samba/sysvol
	read only = No

---

4.16.6 as on my ADC1 seems not available anymore so I am on 4.16.2 
(still from Louis' repo)

To try and sort this out, the lines above what you have posted are 
required, you seem to have posted the lower portion of a python exception.
