Hi,

I have a local repository,  and declare also a remote one,  I want to tell to apt-get to install a package from a local repo, if it exists.  it seems that it begins from the remote .  here is my sources:

deb file:/home/CD1 squeeze main
deb file:/home/extra6 /
deb http://ftp.fr.debian.org/debian squeeze main non-free contrib
 
how to tell that

thanks a lot
best regards
