SyntaxError: invalid syntax during 'Migrate Django-DB'

Hi. I am trying to setup Mailman3 but I get this during the 'Migrate Django-DB' task:

fatal: [lists.example.com]: FAILED! =>

Running a syntax check on the candidate Mailman3 host I get:

$ python -m py_compile settings_local.py 
  File "settings_local.py", line 3
    SECRET_KEY = '[u'1234567890123456789012']'
                                                                              ^
SyntaxError: invalid syntax

Python version on the mailman host is 2.7.13

Any idea?

From the traceback, it seems like you are setting the mailman_production_secret_key as a list, not as a string. This should be a string, along the lines of:

mailman_production_secret_key: '1234567890123456789012'

Yes, you are right! It works now, my fault.

Thanks @JanLuca !
