Как мне это исправить?

Это связано с ошибкой в ftplib и / или urllib : FTP-ответ 226 игнорируется, в результате чего клиент неправильно сопоставляет дальнейшие входящие ответы с исходящими командами.

Я немного покопался и пришел к выводу, что urllib это не может быть полностью исправлено, ftplib как сейчас. Вы можете использовать следующий патч urllib.py , чтобы исправить эту конкретную проблему (разница для Python 2.7.12 ):
