This is an issue in a third-party package. All references to six were dropped in #6615. You can see from the CI we run against all supported versions of Django.

From the traceback, you need to look at your permission classes, see which dependency is causing the issue and update it. (That's more-or-less what the SO thread says too. That's a much better venue for this kind of usage issue.)
