[Samba] ldb errors after upgrade, cause?

[L.P.H. van Belle]

Hai Roel, 


Is samba-dsdb-modules installed ? 

Run : dpkg -l | egrep "samba|winbind|ldb|tdb|tevent|talloc"
That shows it.

Can you try also to run : apt dist-upgrade --autoremove 
Most probley there are some leftovers from the dist upgrade,
You can find these with : dpkg -l |egrep "deb[8-9]|jessie|stretch|debian[8-9]"
As far i can remember your just missing a package, its something simple but simple overlooked.


Greetz, 

Louis
