Ubuntu 11.10 downloads corrupted

Hello,

I downloaded ubuntu-11.10-dvd-amd64.iso, ubuntu-11.10-dvd-i386.iso, ubuntu-11.10-desktop-amd64.iso and ubuntu-11.10-server-amd64.iso. Checksums were always matching, means file has been successfully downloaded. But when I tried to mount it / use as a virtual CD for VMware Fusion, file is not readable / is not a valid cd image file. I tried several servers from different geographical locations with no success. I think most probably everyone else is also having the same issue, because even the torrents also gives the same result. Please look into it.

Thanks,

Have you tryed with virtualbox?
https://www.virtualbox.org/

Even with Virtualbox the same issue exists. Simply the problem is - Files are not valid ISO images on the Ubuntu repository. They are corrupted.

The ISO files seem to be OK. Have you tried burning and actual CD / DVD with them?

The download isos are install media, so don't have a normal root filesystem on them. You use them to first install, then you may run the virtual machine.
Below is my kvm/qemu setup:
$ cat installit
ISO=*iso
NAME=`echo $ISO |cut -f1 -d-`

echo "Creating 6G copy on write image ${NAME}.img"
qemu-img create ${NAME}.img -f qcow2 6G

echo " Using iso ${PWD}/$ISO to create image ${NAME}.img"
kvm -m 750 -cdrom ${PWD}/$ISO -boot d ${NAME}.img
#kvm -m 750 -cdrom /usr/local/vm/natty/natty-desktop-i386.iso -boot d natty.img

Then to run the .img file,
kvm -m 750 *.img

Hi:

I downloaded Ubuntu x64 y x32 tried x32, burned a CD but the ISO does not load. It showed some window that said something about a count not being right but went away the first time I tried but now it does no come up.

I am going to download the file again from Ubuntu but if anybody has any ideas they will be much appreciated.

Did you md5sum check the downloaded iso?
  See https://help.ubuntu.com/community/HowToMD5SUM
Did you burn the cd as slowly as possible?
  See https://help.ubuntu.com/community/BurningIsoHowto
Did you select the media check before trying to install to check the cd?
 https://help.ubuntu.com/community/Installation/CDIntegrityCheck
Did you ever do a "memory check" (another live-media menu choice) on your PC?
Doing the above can save you a lot of time struggling with a bad install media.

Thank you very much

Not possible since I am running Wolf, a hacked version of XP
