dpkg (1.18.4ubuntu1.5) xenial; urgency=medium
* Apply patch from upstream to add frontend locking (LP: #1796081):
- Add support for frontend locking. This makes it possible for frontends
using this new protocol, to safely lock the dpkg database w/o risk of
race conditions with other dpkg instances or frontends supporting the
same protocol.
