System administrators may install and maintain software using tools other than package management software. The Framework system from OPENSTEP was an attempt at solving this issue, by allowing multiple versions of libraries to be installed simultaneously, and for software packages to specify which version they were linked against.įront-ends for locally compiled packages Good package management is vital on these systems. On Microsoft Windows systems, this is also called " DLL hell" when working with dynamically linked libraries. In these systems, complex relationships between different packages requiring different versions of libraries results in a challenge colloquially known as " dependency hell".

Managing dependencies to ensure a package is installed with all packages it requires, thus avoiding " dependency hell"Ĭhallenges with shared libraries Ĭomputer systems that rely on dynamic library linking, instead of static library linking, share executable libraries of machine instructions across packages and applications.

Grouping packages by function to reduce user confusion.

Looking up, downloading, installing, or updating existing software from a software repository or app store.

Ensuring the integrity and authenticity of the package by verifying their checksums and digital certificates, respectively.

Working with file archivers to extract package archives.Typical functions of a package management system include: Package managers are charged with the task of finding, installing, maintaining or uninstalling software packages upon the user's command. Package metadata include package description, package version, and dependencies (other packages that need to be installed beforehand).

Manual actions can include accepting a license agreement or selecting some package-specific configuration options.Ī software package is an archive file containing a computer program as well as necessary metadata for its deployment. Illustration of a package manager being used to download new software. This can be particularly useful for large enterprises whose operating systems are typically consisting of hundreds or even tens of thousands of distinct software packages. Package managers are designed to eliminate the need for manual installs and updates. They work closely with software repositories, binary repository managers, and app stores. Package managers typically maintain a database of software dependencies and version information to prevent software mismatches and missing prerequisites.

Upon installation, metadata is stored in a local package database. Packages contain metadata, such as the software's name, description of its purpose, version number, vendor, checksum (preferably a cryptographic hash function), and a list of dependencies necessary for the software to run properly. Ī package manager deals with packages, distributions of software and data in archive files.

By around 1995, beginning with CPAN, package managers began doing the work of downloading packages from a repository, automatically resolving its dependencies and installing them as needed, making it much easier to install, uninstall and update software from a system. Įarly package managers, like from 1994, had no automatic dependency resolution but could already drastically simplify the process of adding and removing software from a running system. Synaptic, example of a full-featured package managerĪ package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner.
