I am trying to upgrade Xena to Yoga, as a per-requisite i have upgraded kolla to 14.0.0 and started kolla-build for 14.0.0.

following is the error message during the image build, issue occurs only on ubuntu whereas centos has no issues, In my environment we use ubuntu. How can this issue be resolved?
