What about GPL section 3(c) ?

3. You may copy and distribute the Program (or a work based on it, under
Section 2) in object code or executable form under the terms of Sections
1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source
code, ...

b) Accompany it with a written offer, valid for at least three years, to
give any third party, ... the corresponding source code, ...

c) Accompany it with the information you received as to the offer to
distribute corresponding source code. (This alternative is allowed only
for noncommercial distribution and only if you received the program in
object code or executable form with such an offer, in accord with
Subsection b above.)

I'm not assuming. I'm trying to read the GPL rigidly, and section 3(c)
seems to have a provision for this. That is, since I would be
distributing Ubuntu non-commercially, and I received it with said offer
as per section 3(b), I can apply section 3(c) to "accompany [the CD]
with the information I received as to the offer to distribute
corresponding source code".
