On the CheckInstall page (https://help.ubuntu.com/community/CheckInstall), it has a link to ‘Packaging Guide’ (https://developer.ubuntu.com/packaging). However this url is giving 404 at the moment.
What is the right url to ‘Packaging Guide’?
Try Overview — Ubuntu Packaging Guide
I’m not sure if it’s what you want, but my fingers are crossed 
If not that, maybe http://packaging.ubuntu.com/html/ubuntu-dev-tools.html but I’d hope first one
