Keypair elasticluster is present but has different fingerprint #697
Description
When trying to start a cluster via openstack, I get the above error.
Keypair elasticluster is present but has different fingerprint
Here's the -vvv

Could you explain where these keypairs are stored and what they are checked against? The relevant part of my config is below. Changing the user_key_name has no effect, it still checks for keypair elasticluster.

I was able to fix this in a kludgy way by commenting out the lines that throw the exception in openstack.py in the elasticluster code -- and have been able to proceed. But I don't think this is a good long-term solution.

I met with the same issue, and it turned out OpenStack provider loads the key as a DSA key, instead of RSA.

Having the same issue but, this problem is from
paramikoit also was reported issue #1839. Then, I decided to replace paramiko for something more stable so I decide to go with paramiko-ng that is a fork of it. I update the package in the setup.py file.
