I'm also interested in your output from:
and, if you could confirm whether you'd run all 5 of these commands, in this order, and not just the python install one.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install python3.4
sudo apt-get -f install
I think between that and
cat /etc/os-release we should have a good hint as to why you're not seeing that python package.
