Package manager Wikipedia. A 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 computers operating 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 softwares name, description of its purpose, version number, vendor, checksum, 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. The Fink Team wants to bring the full world of Unix Open Source software to Darwin and Mac OS X. We modify Unix software so that it compiles and runs on Mac OS X and. Linux System Administration and Configuration After installation, Linux requires configuration and systems administration. Corporate systems need monitoring, backups. 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 are based on Linux and other Unix like systems, typically consisting of hundreds or even tens of thousands of distinct software packages.

Manual actions can include accepting a license agreement or selecting some package specific configuration options. A software package is an archive file containing a computer program as well as necessary metadata for its deployment. The computer program can be in source code that has to be compiled and built first. Package metadata include package description, package version, and dependencies other packages that need to be installed beforehand. Package managers are charged with the task of finding, installing, maintaining or uninstalling software packages upon the users command. Typical functions of a package management system include Working with file archivers to extract package archives. Ensuring the integrity and authenticity of the package by verifying their digital certificates and checksums. Welcome to The CHIP Operating System. We made a computer. A 9 computer.

Looking up, downloading, installing or updating existing software from a software repository or app store. Grouping packages by function to reduce user confusion. Managing dependencies to ensure a package is installed with all packages it requires, thus avoiding dependency hellChallenges with shared librarieseditComputer systems that rely on dynamic library linking, instead of static library linking, share executable libraries of machine instructions across packages and applications. In these systems, complex relationships between different packages requiring different versions of libraries results in a challenge colloquially known as dependency hell. On Microsoft Windows systems, this is also called DLL hell when working with dynamically linked libraries. Good package management is vital on these systems. 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. Front ends for locally compiled packageseditSystem administrators may install and maintain software using tools other than package management software. For example, a local administrator may download unpackaged source code, compile it, and install it. This may cause the state of the local system to fall out of synchronization with the state of the package managers database. The local administrator will be required to take additional measures, such as manually managing some dependencies or integrating the changes into the package manager. There are tools available to ensure that locally compiled packages are integrated with the package management. For distributions based on. Slackware Linux, there is Check. Install, and for recipe based systems such as Gentoo Linux and hybrid systems such as Arch Linux, it is possible to write a recipe first, which then ensures that the package fits into the local package database. Maintenance of configurationeditParticularly troublesome with software upgrades are upgrades of configuration files. Since package managers, at least on Unix systems, originated as extensions of file archiving utilities, they can usually only either overwrite or retain configuration files, rather than applying rules to them. There are exceptions to this that usually apply to kernel configuration which, if broken, will render the computer unusable after a restart. Problems can be caused if the format of configuration files changes for instance, if the old configuration file does not explicitly disable new options that should be disabled. Some package managers, such as Debians dpkg, allow configuration during installation. In other situations, it is desirable to install packages with the default configuration and then overwrite this configuration, for instance, in headless installations to a large number of computers. This kind of pre configured installation is also supported by dpkg. RepositorieseditTo give users more control over the kinds of software that they are allowing to be installed on their system and sometimes due to legal or convenience reasons on the distributors side, software is often downloaded from a number of software repositories. Upgrade suppressioneditWhen a user interacts with the package management software to bring about an upgrade, it is customary to present the user with the list of things to be done usually the list of packages to be upgraded, and possibly giving the old and new version numbers, and allow the user to either accept the upgrade in bulk, or select individual packages for upgrades. Many package managers can be configured to never upgrade certain packages, or to upgrade them only when critical vulnerabilities or instabilities are found in the previous version, as defined by the packager of the software. This process is sometimes called version pinning. For instance yum supports this with the syntax excludeopenoffice5pacman with Ignore. Pkg openoffice6 to suppress upgrading openoffice in both casesdpkg and dselect support this partially through the hold flag in package selections. APT extends the hold flag through the complex pinning mechanism7Users can also blacklist a package8aptitude has hold and forbid flagsportage supports this through the package. Cascading package removaleditSome of the more advanced package management features offer cascading package removal,6 in which all packages that depend on the target package and all packages that only the target package depends on, are also removed. Comparison of commandseditAlthough the commands are specific for every particular package manager, they are to a large extent translatable, as most package managers offer similar functions.
