Install misses package

[java-artisan]

The install fails because it can't find a package named 'ffi'. For both Python 2 and 3.

This is fixed by running:
sudo apt-get install python3-cffi python-cffi
And restarting the install.

Sadly, python3-ccfi isn't available at the moment.

sudo apt-get install python3-ccfi

[java-artisan]

My mistake, that's a typo. I copy/pasted the Python 2 package name for Python 3. The instruction should read:
sudo apt-get install python3-cffi python-cffi

Thank you, should have recognized it myself.
