I have an Ubuntu 12.04LTS instance on AWS EC2 and I upgraded it to 12.
10 following the instructions at https://help.ubuntu.com/community/QuantalUpgrades.
After upgrading I can no longer ssh into my VM. It isn't accepting my ssh key and my password is also rejected. The VM is running, reachable, and SSH is started. The problem seems to be about the authentication part.
SSH has been the only way for me to access that VM. What are my options?
