Note: There are better ways to do this by now. Check https://docs.docker.com/develop/develop-images/build_enhancements/#new-docker-build-secret-information for details

In order to access packages in private github repositories a Dockerfile might contain statements like this:

RUN git config --global url."https://${GITHUB_TOKEN}@github.com/".insteadOf "https://github.com/"
RUN npm install --ignore-scripts --quiet && npm cache clean --force
RUN git config --global --unset url."https://${GITHUB_TOKEN}@github.com/".insteadOf

Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:
