In order to perform the task of package management effectively, you need to be aware that you will have two types of available utilities: low-level tools (which handle in the backend the actual installation, upgrade, and removal of package files), and high-level tools (which are in charge of ensuring that the tasks of dependency resolution and metadata searching -”data about the data”- are performed). However, most distributions are likely to fall into one of the three distribution families covered by the LFCS certification. It can either be provided by the distribution vendor through central repositories (which can contain several thousands of packages, each of which has been specifically built, tested, and maintained for the distribution) or be available in source code that can be downloaded and installed manually.īecause different distribution families use different packaging systems (Debian: *.deb / CentOS: *.rpm / openSUSE: *.rpm built specially for openSUSE), a package intended for one distribution will not be compatible with another distribution.

Packaging SystemsĪlmost all the software that is installed on a modern Linux system will be found on the Internet. All modern package management systems provide some method of dependency resolution to ensure that when a package is installed, all of its dependencies are installed as well. If a certain package requires a certain resource such as a shared library, or another package, it is said to have a dependency.
