Bug Description

I'm trying to upgrade to Ubuntu 10.4 lucid from a torrent; I found directions
at https://help.ubuntu.com/community/LucidUpgrades#Upgrading%20from%20a%20Torrent

Getting the torrent was no trouble; it took about 20 minutes to get
both the desktop and the alternate image (I didn't realize I needed
the alternate image until I had started getting the desktop image).

$ md5sum *i386*
5b2dadacfd692b4f2d5c7cf034539262 ubuntu-10.04-alternate-i386.iso
d044a2a0c8103fc3e5b7e18b0f7de1c8 ubuntu-10.04-desktop-i386.iso

Then I mounted the image a la:

$ sudo mount -o loop /home/connolly/Desktop/OpenSource/OpenSource-CD/ubuntu-10.04-alternate-i386.iso /media/cdrom0

and then I started the installer:

$ gksu "sh /cdrom/cdromupgrade"

At the "Include latest updates from the Internet?" dialog, I answered "No".
It says quite clearly: "If you answer 'no' here, the network is not used at all."

but then I get a "Do you want to start the upgrade?" dialog that
says "You have to download a total of 1,209M."

I thought perhaps "download" was a misnomer and that it would
get the packages locally, but
 (a) the network went *very* busy (estimating hours to days to complete), so I cancelled it;
 (b) I took the network down with "sudo ifdown eth0" and tried again,
  and it failed altogether

Then I thought perhaps the problem was related to using a mounted .iso image
rather than a physical CD, so I burned the image to CD and tried again.
Same symptoms (with the alternate and then the desktop CD).

I have logs of all of these attempts; I think the one with eth0 down is likely
to have the most information; let's see if I can figure out how to attach it...

Ugh... I don't see any way to attach files.
So I put it in http://pastebin.com/C5S97rRY

Hmm... package "linux" got attached to this question somewhow; I doubt
that's the relevant package, but I'm not sure which is... perhaps update-manager-core?

I gather that unlike Answers, bugs can have files attached, so here's that log file again...

I experienced a similar issue (the installer aborted when I answered "No" to the same question) and have found a simple, provisional workaround - see https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/572634/comments/6.

I don't recall all the details, but I had similar trouble installing Xubuntu 11.10. I ultimately used the alternate installer, and had to skip the network-related steps, and ended up with a buggy install.
