Aptitude is an Ncurses and command-line based front-end to numerous Apt libraries, which are also used by Apt, the default Debian package manager. Aptitude is text-based and run from a terminal. A mutt-like syntax for matching packages in a flexible manner. Mark packages as "automatically installed" or "manually installed" so that packages can be auto-removed when no longer required (feature available in Apt, too, since quite a few Debian releases). Preview of actions about to be taken with different colors marking different actions. The ability to interactively retrieve and display the Debian changelog of all available official packages. Score-based dependency resolver which is more suitable for interactive dependency resolution with additional hints from the user like "I don't want that part of the solution but keep that other part of the solution for your next try". Apt's dependency resolver on the other hand is optimized for good "one-shot" solutions.

fpm is a tool that lets you easily create packages for Debian, Ubuntu, Fedora, CentOS, RHEL, Arch Linux, FreeBSD, macOS, and more! fpm isn’t a new packaging system, it’s a tool to help you make packages for existing systems with less effort. It does this by offering a command-line interface to allow you to create packages easily. FPM is written in ruby and can be installed using gem. For some package formats (like rpm and snap), you will need certain packages installed to build them. Some package formats require other tools to be installed on your machine to be built; especially if you are building a package for another operating system/distribution. FPM takes your program and builds packages that can be installed easily on various operating systems. It can take any nodejs package, ruby gem, or even a python package and turn it into a deb, rpm, pacman, etc. package.
