to my college final year project we planned to setup the private cloud on the two machines.

I recently installed Ubuntu Enterprise Cloud (UEC) on two of my machines . I was trying to install the store image through WebUI. I was able to download Ubuntu 10.04 - (i386) image but while installing, it's giving me following error: -

Command 'euca-upload-bundle' returned status code 1:
Checking bucket: image-store-1296600766
Traceback (most recent call last):
