Today while I was trying to update my Debian Etch I run

apt-get update

then

apt-get upgrade

and I go the following,

The following packages have been kept back and then a list of packages that could not got updated, after googling a little I found that if I enter

apt-get update

and then

apt-get dist-upgrade

the packages were going to got upgraded as they should, so if any of you got that problem hope this could help you solve that.
