Ubuntu :: Does 10.04 LTS Use P2P In Synaptics Or Apt-get Or Another Process

I think I used the command apt-get and synaptics to install some programming library which are

{ autotools-dev, build-essential, cmake, cpp, libboost-thread1.35.0,libboost-thread1.35.0, libboost-thread1.35-dev, libboost-signals1.35.0, libboost-signals1.35-dev,libcv1, libcv-dev, libgdk-pixbuf2, libgdk-pixbuf-dev, libgnomecanvas2-0, libgnomecanvas2-dev, libgsl0, libgsl0-dev, libjpeg62-dev,libtool, libxmu-dev,swig,freeglut3 (for stage), freeglut3-dev (for stage), libfltk1.1 (for stage), libfltk1.1-dev (for stage), libgtk2.0-dev (for stage), libltdl7 (for stage), libltdl7-dev (for stage),libpng12-0 (for stage), libpng12-0-dev (for stage)}

and I didn't use anything else and didn't install any P2P client in Ubuntu. And then a few day later, my laboratory received the message that someone in our laboratory used P2P with prohibited in the university. The people in my laboratory pointed to me because they're all using windows only me using Ubuntu. So I would like to ask "Is it possible that Ubuntu using P2P in its background? or apt-get or synaptics using P2P in their process?" If Ubuntu can't do that, I can prove myself. But If Ubuntu does, I still can show to them that it's Ubuntu's program and it's legal.
