I am trying to upgrade my Django project to Django 2.0, currently the version is 1.8.19. I figured I would do it step by step, firstly upgrading to 1.9, then 1.10 and so on till 2.0. The problem is that I get error message

I have read the thread: Django upgrading to 1.9 error "AppRegistryNotReady: Apps aren't loaded yet."
I have tried using
import django
django.setup()
at the top of my settings.py file with no luck.
I've made an assumption that the problem is with the third party apps. My main question is, how to start checking for invalid third party apps, since commenting them out one by one does not remove the error. I've checked every app's that I've installed via pip documentation, and added the required lines to the INSTALLED_APPS in settings.py. It seems that some packages, such as django-jquery, django-libsass, django-ordered-model have not been developed for some years, however, according to django==1.9 release date, those apps should have worked on django==1.9 (or maybe that is the mistake of my thinking?).
I am ready to post more information from my project if needed.
My settings.py fragment:
INSTALLED_APPS = (
'hvad',
'compressor',
'filebrowser',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'jquery',
'tinymce',
'apps.frontend.ad_akumuliatoriai',
'ordered_model',
'geoposition',
)
The output of "pip freeze":
Django==1.9
django-appconf==1.0.2
django-compressor==2.2
django-filebrowser-no-grappelli==3.7.4
django-geoposition==0.3.0
django-hvad==1.8.0
django-jquery==3.1.0
django-libsass==0.7
