I was trying to install pygame (on 17.10), and it looks like the repository has python-pygame (for python 2.X) but python3-pygame (for python 3) is missing? Here is the actual command that they indicate over on pygame.org to install it:
sudo apt-get install python3-pygame
And yet when I try this it coughs up…
Package python3-pygame is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python3-pygame' has no installation candidate
So what’s going on here, I wonder?
