mew,
Please see below. Also note that the Apt Config File point to testing. So if there are major dependencies problems say from unstable it will not upgrade it. This is to protect you from trashing your system.

In my previous post I mentioned that I commented out everything except the unstable tree. This could be the main reason for me trashing your system.
