Hi,

I am unable to build nova-libvirt image while installing Openstack via kolla (stable/pike).Following is the error I am getting:

Unable to correct problems, you have held broken packages. INFO:kolla.image.build.nova-libvirt ERROR:kolla.image.build.nova-libvirt:The command '/bin/sh -c apt-get update && apt-get -y install --no-install-recommends ceph-common ebtables libvirt-clients libvirt-daemon-system openvswitch-switch pm-utils qemu qemu-block-extra dmidecode xen-utils-4.6 xen-utils-4.6 && apt-get clean' returned a non-zero code: 100

When I run the above command,it gives the error shown below:
