I am not connected to the network and it seems I need build-essentials to get the drivers working. Best I can do is transfer the packages by thumb drive. What is the process for offline installations of the package, and where can I download it?
you can get the download links from the following command
apt-get install --print-uris build-essential
This will give you the download links + other details (hash values + etc). You can use these download links to download the packages. Then you can install the packages by double clicking or using the dpkg command (dpkg -i).
