Re: New Behavior: starcluster addnode error from StarCluster-created master instance

I think it’s an issue with the latest version of boto. Are you using boto-2.33? Downgrading to boto-2.32.0 resolved the issue.

Change the boto version in setup.py and reinstall StarCluster (boto==2.32.0)

The AMI is StarCluster public 64-bit Ubuntu EBS non-HVM (ami-765b3e1f in us-east-1). These instances have been working reliably this way for many months, so it seems like something has changed at AWS? Anyone know of anything?
