well..looking at Xandros sight ..it says its based on debian Sarge..which is a old version..maybe this forum will help you out better..
did you enter su before apt-get??
you type su then it will ask for your root password,,then you can apt-get install
apt-get has no spaces
not sure..but it might use sudo..so
if after entering sudo apt-get install wine
it says it cant find package..you may need to add extra repos to source list..this will help you out..
