I was using Thunderbird and did not expect an error message regarding samba because I didn't do anything with samba,

Thanks for filing this bug in Ubuntu.

I'm seeing many messages like this one in the logs:
Use of uninitialized value $reply in scalar chomp at /usr/share/perl5/Debconf/FrontEnd/Passthrough.pm line 66.

I believe this was fixed some time ago in Ubuntu already. Could you please run these commands one more time to make sure there are no other pending updates?

sudo apt update
sudo apt -f install
sudo apt dist-upgrade

It looks fine now, I believe it was due to the old bug that is now fixed (the one about unitialized values). Also, you should probably remove the segler-alex ppa as it does not have xenial packages.

I'll mark this bug as invalid for samba as it happened in another package, related to debconf, which is now fixed. Please reopen it if you hit this problem again.

Thanks!
