When i tried to open mysql workbench then it saying "ImportError: No module named paramiko; Operation failed: Cannot start SSH tunnel manager" although i have installed paramiko.
I am using python 2.7.3 
ubuntu 12.04

I am getting this error after trying to upgrade from python 2.7.3 to python 3 again i installed python2.7.5 but my gedit not working then coming back to python 2.7.3.
Now everything became normal except mysql work bench.
I am using workbench version 6.0
