[Impact]
 * Missing dep for package maas-cluster-controller added for package so it runs with virsh

[Testcase]
 * sudo apt-get install maas-cluster-controller; python -c 'import pexpect'

[Regression Potential]
 * non-existent, add package dependency

[Raphaël Badin (rvb)]

A new dependency on python-pexpect was introduced in revision 2353. python-pexpect is in main so fixing this is as simple as adding a dependency in the packaging.

This bug was fixed in the package maas - 1.5.2+bzr2282-0ubuntu1

---------------
maas (1.5.2+bzr2282-0ubuntu1) utopic; urgency=medium

  * New upstream bugfix release:
   - Remove workaround for fixed Django bug 1311433 (LP: #1311433)
   - Ensure that validation errors are returned when adding a node over
     the API and its cluster controller is not contactable. (LP: #1305061)
   - Hardware enablement support for PowerKVM (LP: #1325038)
   - Shorten the time taken for a cluster to initially connect to the region
     via RPC to around 2 seconds (LP: #1317682)
   - Faster DHCP leases parser (LP: #1305102)
   - Documentation fixed explaining how to enable an ephemeral backdoor
     (LP: #1321696)
   - Use probe-and-enlist-hardware to enlist all virtual machine inside
     a libvirt machine, allow password qemu+ssh connections.
     (LP: #1315155, LP: #1315157)
   - Rename ppc64el boot loader to PowerKVM (LP: #1315154)
   - Fix NodeForm's is_valid() method so that it uses Django's way of setting
     errors on forms instead of putting text in self.errors['architecture']
     (LP: #1301465)
   - Change BootMethods to return their own IReader per-request, update method
     names to reflect new usage. (LP: #1315154)
   - Return early and stop the DHCP server when the list of managed interfaces
     of the nodegroup is empty. (LP: #1324944)
   - Fix invalid attribute references in the VirshSSH class. Added more test
     for the VirshSSH class. (LP: #1324966)
  * debian/control:
   - Add missing dependency in maas-cluster-controller for python-pexpect
     (LP: #1322151)
