[Samba] Problem with libldb1

[Viktor Trojanovic]

I just ran "apt upgrade" on my DC (Ubuntu 18.04, Samba 4.10 from Louis
Repo) and it ended with error messages about unmet dependencies in regards
to libldb1.

root at DC1:~# apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python3-ldb : Depends: libldb1 (= 2:1.5.5-1bionic~1) but
2:1.5.4-1ubuntu1.2 is installed
 python3-samba : Depends: libldb1 (>= 2:1.5.5~) but 2:1.5.4-1ubuntu1.2 is
installed
                 Recommends: python3-gpg but it is not installed
 samba : Depends: libldb1 (>= 2:1.5.5~) but 2:1.5.4-1ubuntu1.2 is installed
 samba-dsdb-modules : Depends: libldb1 (> 2:1.5.5~) but 2:1.5.4-1ubuntu1.2
is installed
 samba-libs : Depends: libldb1 (>= 2:1.5.5) but 2:1.5.4-1ubuntu1.2 is
installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or
specify a solution).

I read some older threads here that say that an error with libldb1 is
expected due to some change in the ldb tools but it also says that the
command apt --fix-broken install should fix it which it apparently does not
for me.

Use 'apt autoremove' to remove them.

Would appreciate your advice on how to go from here.

Thanks,
