Comment puis-je résoudre ce problème?

Answer 1

Ceci est dû à a bug in ftplib and/or urllib: La réponse FTP 226 est ignorée, provoquant une correspondance incorrecte du client avec les commandes sortantes. J'ai fait quelques recherches et suis arrivé à la conclusion que urllib ne peut pas être entièrement corrigé avec ftplib comme c'est maintenant. Vous pouvez utiliser le correctif suivant pour urllib.py pour résoudre ce problème particulier si (la diff est pour Python 2.7.12):
