As I've had no need or desire to do that, I have no idea how the
regular apt-get would behave when run on a system that hasn't been
"finalised" (for want of a better term). AIUI many of the programs
that run in the d-i are hacked-about versions installed from udebs,
or wrapped up in the swiss-army penknife, busybox. Perhaps just be
patient and let the d-i "close".
