I know. This is Bug #821002, which is also serious and should be fixed soon.
If you still want to work around the problem and not wait for +deb8u3,
you could maybe:

dpkg --purge --force-depends samba
apt-get -f install

This will probably install samba (again) and samba-libs version +deb8u2,
but this time without errors.

After that you can use aptitude, deborphan, debfoster, or whatever
work best in your case.
