+System dependencies on Debian distributions like Ubuntu are described by `<package-name>.deb` files. These are
+typically installed using CLI tools such as `apt` or `dpkg`. This buildpack implements logic to install packages

+that could invalidate how [CNB rebasing][cnb-rebase] functionality works.
