try patching /usr/local/lib/python3.7/dist-packages/duplicity/backends/webdavbackend.py", line 291
from
  return u'Basic %s' % base64.encodestring(auth_string).strip()
to
  return u'Basic %s' % base64.encodestring( bytes(auth_string, "utf-8") ).strip()

and see if that works. if so please tell us so we can patch this bug accordingly.

Thanks, not solved yet, but we're close. Below is the current output. The call actually goes through to the server. BUT, where the asterisks are is the Base64 encoded password... and it has a leading " b' ", which my working duplicity install does NOT have. I am not sure if that is a part of the newly created byte array, are that it gets added somewhere else when the byte array is printed.
