cd ~/src/github.com/jblakeman/apt-select
python setup.py build
sudo python setup.py install

pip install apt-select

OK so now I have the freshly generated config so install it per instructions

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup &&   sudo mv sources.list /etc/apt/

so now do an update

sudo apt-get update && sudo apt-get upgrade
