I had a similar problem, and so I appreciate this information.  But my
understanding is still a bit shaky.  Could someone point me to an
appropriate doc which explains why `APT::Default-Release "stable";' has
to be removed from /etc/apt/apt.conf' in order for the downgrade to take
place? ... or else perhaps could someone post a short explanation here?

Since we are talking about downgrading to `stable', I don't understand
why the presence of `APT::Default-Release "stable";' would prevent that.

Thanks.
