There are a handful of methods for loading of TexLive onto a non-networked machine.
Depending on your requirements, this is often better than loading from the Ubuntu repositories as they lag behind the latest and greatest from tug.org. TeX/LaTeX is relatively free of system dependencies, so you are unlikely to have issues installing as you might with more tightly coupled packages.
