hi all..

brand new install of Debian 4.9.51-1 on aws. using apt-get for some stuff. get to run:

# sudo apt-get build-dep python-imaging --fix-missing

get:

"E: You must put some 'source' URIs in your sources.list"

# sudo vi /etc/apt/sources.list

shows this:

deb http://cdn-aws.deb.debian.org/debian stretch main

deb http://security.debian.org stretch/updates main

deb http://cdn-aws.deb.debian.org/debian stretch-updates main

what else do i need to add to /etc/apt/sources.list

thanks...
