Re: argh! aptitude/dselect/apt-get dieing????
Very nice writeup.
Question, what if you want foo from unstable and it requires a version
of bar in unstable but your existing bar is from testing? What if bar
isn't installed at all and the requirement is going to install it? Will
apt do the right thing at this point?
