Hi, check security groups. It is likely that you don't have the ports/protocols that you are using for Ubuntu updates like HTTP (TCP 80), HTTPS (TCP 443) You might use curl/wget from your VM to check those things.

IGN is not an error.

Normally, outgoing traffic is not limited, so security groups are not at issue.

On the other hand, search for "waiting for headers" and "hang", and you will find plenty of suggestions how to tackle this problem. Have you tried other images than Ubuntu?
