Right, same here. But this time it is not due to the hplip-data version -- it is surely due to the ongoing qt transition, although I have not tracked down the exact reason that affects hplip. There are also lots of KDE packages to be removed, if you use a KDE desktop.
You can use
apt full-upgrade -d
and download the packages to be updated, but not do the installation. That way, when the dependency conflicts are resolved, the full-upgrade will not take as long.
