What to edit sources.list with to install packages?

Hi, I am working with the zcu104, running pynq 2.5

I am attempting to load pygame. However, I don’t know what to edit the sources.list file on the board so that I can load the pygame libraries from the proper repository. I have typed in some ubuntu repositores (for want of experiment) but they were ignored.

When I type:

sudo apt-get build-dep python-pygame

I get a warning saying that “You must put some ‘source’ URIs in your sources.list”.

Where is the list of legal repositories that I might load into the sources.list file?

Thank You
Tom
