I installed paramiko in my Ubuntu box "sudo apt-get install python-paramkio". 
But when import the paramiko module i am getting error.
ImportError:No Module named paramiko
When i list the python modules using help('modules'). i couldn't find paramiko listed.
To use python libraries, you must have development version of python like python2.6-dev, which can be installed using sudo apt-get install python2.6-dev.
Then you may install any additional development libraries that you want in your code to run.
Whatever you install using sudo apt-get install python-paramkio or python setup.py install will then be available to you.
paramiko installation " Unable to import ImportError"
