Setting up uvtool-libvirt (0~bzr99-0ubuntu1) ...

libvirtd does not appear to be listening on "/var/run/libvirt/libvirt-sock".
On Ubuntu, libvirtd is managed with the "libvirt-bin" upstart job.
Repair libvirtd, then reconfigure uvtool-libvirt with:
    sudo apt-get -f install
dpkg: error processing package uvtool-libvirt (--configure):
 subprocess installed post-installation script returned error exit status 1
