Yes, That's what I've always read so I have always used aptitude but in
this instance I have packages that will not upgrade via aptitude. I
mention this case specifically as the Debian docs[1] say "aptitude is
the recommended package manager for Debian".

I post this question with the intent to investigate why I might need to
familiarize myself more with APT as it's evident there are use cases
where aptitude cannot get the job done. I have struggled with situations
similar to this only rarely and could have possibly saved my self some
time knowing the nuances of APT (Debian indeed has one of the most
diverse set of package management tools around). With that in mind,
consider the following on this Debian Wheezy based system (apologies in
advance for the length of this post, but it seems pertinent to include)...
