Package manager
software that manages the installation, upgrading, removal and dependency resolution of software packages
A package manager, or package management system, is software that supports installing, upgrading, configuring, and removing software for the host system in a consistent manner.
A package manager deals with packages, distributions of software and data in archive files. Packages contain metadata, such as the software's name, description of its purpose, version number, vendor, checksum (usually a cryptographic hash function), and a list of dependencies necessary for the software to run properly. Upon installation, metadata is stored in a local package database. Package managers typically maintain a database of software dependencies and version information to prevent software mismatches and missing prerequisites. They work closely with software repositories, binary repository managers, and app stores.
Package managers are designed to eliminate the need for manual installs and updates. This can be particularly useful for large enterprises whose operating systems (OSes) typically consist of hundreds or even tens of thousands of distinct packages.
History
An early package manager was SMIT (and its backend install) from IBM AIX. SMIT was introduced with AIX 3.0 in 1989. Package managers like dpkg have existed as early as 1994.
“Package manager” enters the record as software that manages the installation, upgrading, removal and dependency resolution of software packages. Crown Archives preserves that source wording while asking what Package, manager and software can confirm, complicate or overturn.
Why this record matters
“Package manager” is worth following because a concise public description often conceals a longer documentary argument. Here, Package, manager and software provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 24, 2026.

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
