[Pkg-libvirt-maintainers] Bug#758994: Can't install package because "Unit virtlockd.service cannot be reloaded because it is inactive"

[Giuseppe Sacco]

Package: libvirt-daemon-system
Version: 1.2.7-10+b1
Severity: important

Today I updated my Jessie machine and got this error:

giuseppe at blatta:~$ sudo env LANG=C apt-get -f install
[...]
Setting up libvirt-daemon-system (1.2.7-10+b1) ...
Job for virtlockd.service failed. See 'systemctl status
virtlockd.service' and 'journalctl -xn' for details.
dpkg: error processing package libvirt-daemon-system (--configure):
 subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of libvirt-bin:
 libvirt-bin depends on libvirt-daemon-system (>= 1.2.7-10+b1); however:
  Package libvirt-daemon-system is not configured yet.

dpkg: error processing package libvirt-bin (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libvirt-daemon-system
 libvirt-bin
E: Sub-process /usr/bin/dpkg returned an error code (1)


As you may see, package cannot be configured and stopped the machine
upgrade.

More information, as suggested by the error message, are:
