Fix pushed to lp:~kirkland/maas/1274448

This bug was fixed in the package maas - 1.5+bzr1909-0ubuntu1

---------------
maas (1.5+bzr1909-0ubuntu1) trusty; urgency=low

  * New upstream release.

  [ Dustin Kirkland ]
  * debian/maas-region-controller-min.postinst: Fix typo in sed. Remove
    double quotes. (LP: #1274448)

  [ Andres Rodriguez ]
  * debian/control: Add depends on python-crochet.
  * Get rid of dfsg on the versioning as we no longer strip any code from
    the orig tarball.
    - debian/rules: Do not strip any files out of the tarball.
  * debian/patches/*: Refreshed.
