Mirantis Fuel 7/ unable to run apt-get install python-pip

Setup Mirantis Fuel 7 to be an apt-cacher. Installed the calico plugin from github, not from the mirantis website. The one on the Mirantis website is old. After doing this, apt-get install python-pip in the calico-controller.sh script fails to run. Changing it to easy_install pip fixes the problem for me.
Looks like the apt-cacher doesn't include that component. Python-pip resides in 'universe' component.

Thanks @linuxsimba for reporting this. I see two overall problems here:

    Our install scripts don't work with the Fuel master as an APT cacher; instead they require external access.

    The Calico plugin on the Mirantis website needs updating.

We're going through Fuel 7 certification at the moment, so that will address the second point. Current ETA for that is March/April.

The first point will require longer term work, and I don't think we'll address it for our Fuel 7 plugin. After the easy_install pip change that you mentioned, I would still expect later installs in the script to go wrong - is that what you observed?

calico plugin installed with no problem under 2 conditions

    external connectivity to openstack nodes because calico plugin repo are not cached by fuel apt-cacher.

    easy_install pip instead of apt-get install python-pip because I was using the apt-cacher.

Even without the "easy_install pip" change, the only portion of the bash script calico_controller.sh that failed was minor. Not sure what "pyinotify" and "pyaml" do. I saw no recognizable change in the behaviour of the setup with this minor failure.
