Comment 3 for bug 798998

This affects me too, but I'm having no joy with the one-liner fix.

I am using Diablo on Ubuntu 11.10 and edited /usr/lib/python2.7/dist-packages/nova/api/ec2/cloud.py
Restarted services but still get the following when I issue the following

euca-modify-image-attribute ami-00000002 -l

The problem I have is that my images are being uploaded as private and I need to be able to change them to public so all projects can use them.
