I am trying to upgrade from either Hardy Heron or Intrepid Ibex (sorry, I did not check which one) using the ubuntu-9.04-rc-alternate-i386.iso image from http://mirrors.us.kernel.org/ubuntu-releases/jaunty/. When I mount the image and do this command:
The installer comes up and apparently fetches the same packages three times, then it finally fails with this error:gksu "sh /cdrom/cdromupgrade"
I would simply perform a network update, but for some reason, Ubuntu doesn't seem to like my network card anymore, therefore it will not let me connect to the Internet, or even my own router/network.Could not download the upgrades. The upgrade is now aborted. Please check your Internet connection or installation media and try again. All files downloaded so far are kept.

I am on a ThinkPad R51e with an 11b/g Wireless LAN Mini PCI Adapter and a Broadcom NetXtreme Fast Ethernet card.
I am dual booting with Windows XP. Partitions are NTFS, FAT, and ext3.
I doubt this would matter, but the iso image is on my Windows partition. I can't copy it because my HDD my be damaged, and it will not copy large files across partitions, no matter which OS I use to copy the image.
