Public bug reported:
I downloaded the "alternate" (i386) ISO, made sure the checksum was correct,
then burnt it on a CD, slowly (x6) as usual. I rebooted with that CD in the
drive, then to avoid wasting time with a potentially faulty CD, I ran the CD
integrity test, before going any further in the installation process. The test
failed instantly ! :-/
I tried burning the ISO twice (on a CD-R first, then on a rewritable CD), and
both times it choked instantly, on the very same file. I found that
suspicicous... from a statistic point of view...
It failed on this file:
./dists/edgy/main/binary-i386/Release
On the CD, I looked in /md5sums.txt, it shows that the supposedly faulty file
is the very first file that's being checked. I ran md5sum manually on that
file, to see for myself if the checksum was indeed faulty, but as I was
suspecting.. it was NOT faulty !
File checks ok, but the CD self test pretends it is faulty.
As a last test, to rule out any media and optical drive problems (although at
this stage they were already pretty much considered innocent), I ran the CD
self test directly from the ISO file itself, by running the CD through VMware.
And again, the CD integrity check pretended that the first file was faulty !
At this point it seemed pretty evident that the CD test failed but that
the CD was actually probably perfectly ok, so I proceeded with the
installation. The install went very well and after an hour fiddling with
the desktop, everything appers to be working just fine.
