[StarCluster] Starcluster start cluster stuck at Configuring passwordless ssh for root

[Justin Riley]

Hi Jonathan,

Very strange - both AMIs work for me no problems. What version of
PyCrypto are you using? You can check this by running:

$ python -c 'import Crypto; print Crypto.__version__'

If it's not 2.5 I'd suggest upgrading PyCrypto and see if that solves
the problem:

$ easy_install -U pycrypto

Also, StarCluster keeps a log in ~/.starcluster/logs/debug.log which
might be useful in figuring out what the issue is.

I'm also on #starcluster on IRC (freenode) if you want to debug this in
real-time.

Using restart successfully reboots the cluster but then gets stuck at the same point during configuration. I also created a new ssh key using the procedure in the quick-start, and reset the cluster template to use the newly generated ssh key.

When I try to start the cluster everything works fine, it starts up two m1.small instances in my EC2 account, and successfully goes through the whole startup, until it gets to Configuring passwordless ssh for root, and then stops, and stays there indefinitely (I stopped it after 45 minutes and terminated the cluster)
