Solution
Update the latest version of Flask:
pip uninstall flask
pip install flask==0.12
pip install flask-login
Patch the /usr/lib/ckan/datapusher/lib/python2.7/site-packages/ckanserviceprovider/web.py and replace import flask.ext.login as flogin with import flask_login as flogin
Restart datastore and ckan service:
sudo a2ensite datapusher
sudo service apache2 restart
Check the http://127.0.0.1:8800:
And the “Upload to DataStore” function should be fixed:
