Yes yes yes i got it working too thank you @EdwardMarshall for your input.

Now i was also having issues with the rrdtool so i followed the same method as you sent but for the rrdtool.

sudo apt install python-rrdtool

Followed by

cd /opt/minemeld/engine/current/local/lib/python2.7/site-packages

Then

mv rrdtool.so rrdtool.so.old

Finally

ln -s /usr/lib/python2.7/dist-packages/rrdtool.x86_64-linux-gnu.so rrdtool.so

Restart Minemeld

sudo -u minemeld /opt/minemeld/engine/current/bin/supervisorctl -c /opt/minemeld/local/supervisor/config/supervisord.conf start

If you have issues with the minemeld web or minemeld engine starting and you check the logs and see the errors on flask.ext.login being depreciated use flask_login. find and replace flask.ext.login with flask_login on the aaa.py file under /opt/minemeld/engine/current/lib/python2.7/site-packages/minemeld/flask

good luck
