[ale] apt-get ques for Debian users

[Jay Loden]

I run Debian (Mepis install, basically Debian Testing/Unstable) on my laptop, 
and I have been using apt-get quite happily for about a month or two now.  
However, I recently had a huge number of packages upgrade after an apt-get 
upgrade (I'm assuming because of the new Debian 3.0r4), and now I have a 
whole big list of "packages kept back" when I do apt-get upgrade.  

What does this mean, and why are they being held back?  They look to be mostly 
updated KDE packages.  Should I be doing apt-get dist-upgrade ?  Are they 
being held back due to possible conflicts?
