Having Kids

The fact is, most of the freedom I had before kids, I never used. I paid for it in loneliness, but I never used it.

This is a guide on setting up private apt repository that is accessible over a local network via HTTPS and is signed to avoid having to use –allow-unauthenticated to install packages.

For my use case I have two distributions of packages, they are production and test distributions. The packages in each distribution varies based on what I have approved to be used in a live/production environment versus a test environment.

If you are only using one distribution modify the instructions accordingly.

Most web apps need login information of some kind, and it is a bad idea to put them in your source code where it gets saved to a git repository that everyone can see.
