You can sort of do dpkg -i but it's messy because it won't get the order right. You make your download scripts in Synaptic and put them on something like a USB stick, take that to an online machine (needs to have wget) and do the downloads, then bring the USB stick back and let Synaptic do the installs. You need to somehow get the lists of files (apt-get update) and install Synaptic, after that it's pretty easy. The corresponding item is File -> Add downloaded packages which prompts for a directory where the files are, then installs them correctly just as if you were online.

Then do File -> Generate Package Download Script and it will output a script that calls wget for each file.

It isn't very well set up for a lack of internet, in some of the BSDs you can do a 'make fetchlist' which will give you a list of files (and urls?) you need to download to install something.Īptitude may do this too, but in Synaptic you can select things you want to install, and it will also include needed dependencies automatically.
