picking the packages from
/var/cache/apt/archives it
goes to some thing like
 http://us.archive.ubuntu.com/ubuntu/ precise/main qemu-utils amd64
1.0+noroms-0ubuntu13 [353 kB]
and so on and is downloading things in /var/cache/apt/archives

I've never tried this (never had any need to), but it sounds plausible

No it does not assume they are downloaded , it actually is downloading them
again and this is what I do not want to happen.
