I have a network that has no internet connectivity from any of the devices. The only way I can get data on it from the outside world is via a USB mass storage device (USB stick, external hard drive, external CD/DVD drive).

apt as I would if I were on an internet-connected machine. However, installing software via
apt is something I would like to do.
