Python3-Venv Not Installed Ubuntu 14.04

Fresh install of ubuntu gnome 14.04, followed by dist-upgrade

one of the first things I tried to do was create virtual environment for python

python3 -m venv flask

gave me

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

which is odd because i thought venv was installed by default, but anyways

sudo apt-get install python3-venv

gives me

E: Unable to locate package python3-venv

am I missing something? is something wrong with my python installation? i've tried to google whether there's a repo or something i need but I can't find one.
