On running following command

pip install --upgrade pip

it shows following error even I can't install any other packages as it says upgrade pip first.

The problem is not with pip's version, but with ssl. The version of python you installed does not have the ssl module, which can occur if you compiled python without installing the libssl-dev headers. (Or the version you downloaded was made so).
