updating packages

[Brian May <brian@linuxpenguins.xyz>]

Hello,

I have started updating packages, trying to fix Django 1.11 issues where
applicable, but seem to be running into road blocks for everything I
try. Have updated git. Help appreciated:

* django-filter, requires djangorestframework.
* djangorestframework, tests fail, not yet investigated in detail why.
* celery: requires cyanide (including docs) and sphinx_celery to be packaged in Debian.

Thanks.
