Hello,

I am new to Keystone and I am using the Fiware guide to install Keystone and Horizon. However, during the Keystone installation, I am getting an error at step 3 command:

sudo python tools/install_venv.py

The log is as below:

Since I am new to Keystone, I do not understand why is this error occuring. I am using Ubuntu 16.04.1 and it is updated.
