Bug report: bad disk but self-test succeeds

I see, though I suggest the list be bothered with this because it is a problem and needs to be aired out and addressed. I will copy the list in this reply.
I'm not interested in blame, really, as much as finding your problem and getting rid of it. I understand your disappointment, and I don't want your disappointment to happen to anyone else.
I don't understand the CD verification process enough to use that as the basis for any conclusions or assumptions.
The error message that you wrote suggests, by speaking of missing files and such, that the filesystem of the iso was modified between the Edubuntu project and its pressing, which is why I suggested going to them.
"Do these people use the official image directly without modification?" needs to be established.
If so, "are they receiving this complaint from other customers?" is another question worth pursuing.
My experience wouldn't serve in any technical capacity to help fix this problem, I merely suggest a way forward.

Hi Simon,

I don't want to bother the entire list with this, but I thought I'd try to
explain a bit better.

On-disk is the U.S. company that the edubuntu website suggests as the place
to purchase nicely pressed and packaged disks.  I did send a complaint to
them, but I can only blame them to a small extent.

The disk has a self-test, which passes!

If they are being responsible and running the disk's own diagnostic after
pressing it, over and above verifying the image, then they still would have
thought the product was working.  The only way they seemingly would be able
to tell that there is a problem is if they actually tried to install on a
machine.  This is an edubuntu quality control issue, not an vendor one.

Bad disks happen.  The .iso that I burned worked fine.  I'm reporting a
problem with verification, and especially with user experience.  Better
install-disk self-testing can mean the difference between a user who gets
the impression that everything in "the Linux world" is the user's problem,
and a user who installs it and learns.

Best wishes,
