If this solution did not work for you, what have you tried to do to fix the issue?

The " Exhausted available authentication methods" exception indicates that there is a misconfiguration on the host whereby the user specified cannot authenticate via SSH.

Try using SSH from the command line of another host and use the same user that you are entering in the installation wizard to attempt to authenicate to one of the nodes you are attempting to add to the cluster.

- if you are using "root" then ssh as "root" is disabled by default on some OSes... you might check that.

- if you are using a non-root user, then verify that sudo, you might need to configure your sudoers with something like "userid ALL=(ALL)NOPASSWD:ALL"

Using ubuntu 14.04 LTS Heres a snap of my sudoers file

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

What changes must be made ?
