3. wget http://archive.ubuntu .com/ubuntu/dists/artful/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/linux # Download ubuntu's network installation file
4. wget http://archive.ubuntu.com/ubuntu/ dists/artful/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/initrd.gz # Download ubuntu's network installation file
