[Python-modules-team] Bug#961177: django-simple-captcha: Not compatible with Django 3.x

[Chris Lamb]

Source: django-simple-captcha
Version: 0.5.6-2
Severity: normal
User: python-modules-team at lists.alioth.debian.org
Usertags: django-3.x
Control: affects -1 plinth

Dear maintainer,

The version of Django experimental is currently 3.0.6-1. I have built
the 153 reverse-dependencies in unstable against this version and 114
of these build & pass their testsuite successfully. For more
information, see:

    http://bugs.debian.org/960890

Please use the above bug report for queries or questions regarding
Django 3.x that are not specific to this particular package in order
to reduce duplicated work across all of the bugs.

Whilst django-simple-captcha itself builds from source, it causes
other packages (eg. plinth) to FTBFS.

Here is the FTBFS from plinth:
