I am not sure but I think it was me :)

The apt-get and adept routes of installing and updating work great ... 
until there is a problem. If there are dependencies problems they simply 
say "broken" or "## packages will not be installed". They do not help at 
all in identifying or resolving the conflict.

The aptitude program is much smarter about that. If it sees a conflict, 
it will tell you what it is and even offer possible solutions. Its 
ability to ferret out solutions is actually quite amazing.

As far as I can find there are numerous "blessed" means for updating 
your system: apt-get, aptitude, adept, update-manager, synaptics and 
probably others. They are just alternatives with varying interfaces and 
function. For example, adept is not your friend when X will not start...

I always do a safe upgrade first so that I can see what the packagers 
have decided are safe and which ones are not. Rarely do I not accept the 
implied "not-safe" updates. I just like knowing that I am stepping onto 
less solid ground and if things go south I look at those updates first.

I think that Chuck is saying that it did not and is confused by the 
fact. Frankly I am too. What you say, I believe to be true but Chuck's 
experience is to the contrary. If ever I run into the same problem, I 
will take Chuck's advice and look at the archives to insure that they 
are indeed being cleaned.
