Broken Pipe when updating templates

OpenNebula 4.14 Beta
OS: Ubuntu Trusty / 14.04.3

Followed exactly http://docs.opennebula.org/4.14/design_and_installation/building_your_cloud/ignc.html

After creating a template, if you tried to update it by adding new variable definition as ‘oneadmin’, I get the following upon saving the changes:

~$ onetemplate update 0
Broken pipe
