Can't call method "subModel" on an undefined value at /usr/share/perl5/EBox/Samba.pm line 336

After updating Zentyal from 5.1 to 6.0 the package zentyal-samba does not complete the update process due to this error:

root@server-z1:/# dpkg --configure -a
Setting up zentyal-samba (6.0.1) ...
Can't call method "subModel" on an undefined value at /usr/share/perl5/EBox/Samba.pm line 336.
dpkg: error processing package zentyal-samba (--configure):
 installed zentyal-samba package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 zentyal-samba

I tried to uninstall and reinstall zentyal-samba but the problem is the same.
The Samba module is unusable, so this is a big problem.
I searched for this problem but I did not find anything resolutive.

Could you help me please?
Thanks!

I solved purging the package zentyal-samba and reinstalling it from scratch.
But after this the user and group list in the Samba module became empty, so this is not a valid resolution.

The conditional at line 333 in Samba.pm is only used to add a service configuration for samba at TCP ports 49152 - 65535. I worked around this by temporarily modifying the conditional to if (0) { ... so that it wouldn't try and execute this. I then added the service configuration manually in the web interface. Everything seems to be OK so far.

Thank you for reporting this, we cannot reproduce the issue so we think that is an isolated issue.
