I wonder if this shouldn't be hardcoded into apt-get in some way.
How about this:
If any essential (or only apt + depends) packages are to be updated do
a run installing only the essential packages and their requirements
first. Then restart yourself adding a -y to the options.
This could be combined with a check if a lot of packages (say if it
has to break cycles into multiple dpkg calls) to avoid double runs on
day-to-day updates.
