You are mistaken here. python-pygame is only a python 2.7 pygame. you want python3-pygame. https://packages.debian.org/search?keywords=python3-pygame Speaking as a debian user are going to have a _whole lot of this_. If you don't know about apt-cache search <pkgname> let me recommend it to you. This on debian unstable: lac@smartwheels:~$ apt-cache search pygame lightyears - single player real-time strategy game with steampunk sci-fi psychopy - environment for creating psychology stimuli in Python python-pygame - SDL bindings for games development in Python python-pyglet - cross-platform windowing and multimedia library pyntor - flexible and componentized presentation program solarwolf - Collect the boxes and don't become mad python-soya - high level 3D engine for Python python-soya-dbg - high level 3D engine for Python - debug extension python-soya-doc - high level 3D engine for Python python3-pygame - SDL bindings for games development in Python (Python 3) So, too many hits, alas, but it does tend to find such things.
