Answer 1

The get_core_apps has been removed since django-oscar-2.0, as is described in the release notes:

Removed oscar.get_core_apps. Overriding apps is now done by replacing the Oscar app entry in the INSTALLED_APPS setting with that of the forked app.

You thus should remove the get_core_apps, and alter the INSTALLED_APPS instead. For example:

INSTALLED_APPS = [
    # Django apps
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'django.contrib.flatpages',

    # oscar apps
    'oscar',

    # your apps
    # ...
]
