[Voyage-linux] apt-get -y upgrade breaks installation && other

[binary]

hi. i am running voyage linux and i am doing an apt-get upgrade.
then it tries to download headers, but it cannot find it. then it breaks 
the installation. i am trying to download manually the headers and 
install it but the installation goes all wrong.
all i want to do is apt-get install linux-headers-$(uname -r) which it 
does not work. it fails for me in all versions from 0.8.5 and upwards.

on the contrary the version 0.8.0 works fine and i have no issue at all. 
apt-get upgrade -y works fine.

any ideas?
