PackageKit
PackageKit is a free and open-source suite of software applications designed to provide a consistent and high-level front end for a number of different package management systems. PackageKit was created by Richard Hughes in 2007, and first introduced into an operating system as a default application in May 2008 with the release of Fedora 9. The suite is cross-platform, though it is primarily targeted at Linux distributions which follow the interoperability standards set out by the freedesktop.org group. It uses the software libraries provided by the D-Bus and Polkit projects to handle inter-process communication and privilege negotiation respectively. PackageKit seeks to introduce automatic updates without having to authenticate as root, fast-user-switching, warnings translated into the correct locale, common upstream GNOME and KDE tools and one software over multiple Linux distributions. Although bug fixes are still released, no major features have been developed since around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNOME Software
GNOME Software is a utility for installing applications and updates on Linux. It is part of the GNOME Core Applications, and was introduced in GNOME 3.10. It is the GNOME front-end to the PackageKit, in turn a front-end to several package management systems, which include systems based on both RPM and DEB. The program is used to add and manage software repositories as well as Ubuntu Personal Package Archives (PPA). Ubuntu replaced its previous Ubuntu Software Center program with GNOME Software starting with Ubuntu 16.04 LTS, and re-branded it as "Ubuntu Software". It also supports fwupd for servicing of system firmware. GNOME Software removed Snap support in July 2019, due to code quality issues, lack of integration (specifically, the user can't tell what snap is doing after they click "install" and that it generally ignores GNOME's settings), and the fact that it competes with the GNOME-supported Flatpak standard.

Apper
Apper (originally named KPackageKit) is a free and open source Linux front-end application for the PackageKit package management service by KDE. Apper also has one main difference compared to the old KPackageKit: Apper can list applications instead of listing only packages. This makes it much more user-friendly and allows the user to search for and install applications without the added complexity of dealing with packages and dependencies. Besides installation of new applications it also allows easy removal and updates. It can be compared to the Ubuntu Software Center as well as the AppStream project. Apper has been adopted by a few distributions such as Fedora, Debian and openSUSE openSUSE () is a free and open source RPM-based Linux distribution developed by the openSUSE project. The initial release of the community project was a beta version of SUSE Linux 10.0. Additionally the project creates a variety of tools, s ... 12.1. References External links * – Devel ...

DNF (software)
DNF or Dandified YUM is the next-generation version of the Yellowdog Updater, Modified (yum), a package manager for .rpm-based Linux distributions. DNF was introduced in Fedora 18 in 2013, it has been the default package manager since Fedora 22 in 2015, Red Hat Enterprise Linux 8., and OpenMandriva; and also an alternative package manager for Mageia. Perceived deficiencies of yum (which DNF is intended to address) include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver. DNF performs package management tasks on top of RPM, and supporting libraries. DNF was originally written in Python, but efforts are under way to port it to C and move most functionality from Python code into the new libdnf library. libdnf is already used by PackageKit, a Linux distribution-agnostic package system abstraction library, even though the library does not have most of DNF's features. Adoption DNF has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Package Management System
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 computer 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 (preferably 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 ent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Packaging Tool
Advanced package tool, or APT, is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian, and Debian-based Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code. Usage APT is a collection of tools distributed in a package named ''apt''. A significant part of APT is defined in a C++ library of functions; APT also includes command-line programs for dealing with packages, which use the library. Three such programs are apt, apt-get and apt-cache. They are commonly used in examples because they are simple and ubiquitous. The ''apt'' package is of "''important''" priority in all current Debian releases, and is therefore included in a default Debian installation. APT can be considered a front-end to dpkg, friendlier than the older ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNOME Core Applications
GNOME Core Applications is a software suite of approximately 30 application software that are packaged as part of the standard free and open-source GNOME desktop environment. GNOME Core Applications have the look and feel of the GNOME desktop, and often utilize the Adwaita design language. Some applications have been written from scratch and others are ports. The employment of the newest graphical widgets offered by the latest version of GTK in order to implement the GNOME Human Interface Guidelines (HIG) ergonomically is the only feature which all GNOME Core Applications have in common. Some of the GNOME Core Applications are essential, while several are not, e.g. GNOME Weather. Most are graphical front-ends, e.g. GNOME Software, to underlying Linux system daemons, like e.g. journald, PackageKit, NetworkManager or PulseAudio. Configuration * Settings – main interface to configure various aspects of GNOME. Diverse panels represent graphical front-ends to configure the ...

Polkit
Polkit (formerly PolicyKit) is a component for controlling system-wide privileges in Unix-like operating systems. It provides an organized way for non-privileged processes to communicate with privileged ones. Polkit allows a level of control of centralized system policy. It is developed and maintained by David Zeuthen from Red Hat and hosted by the freedesktop.org project. It is published as free software under the terms of version 2 of the GNU Lesser General Public License. Since version 0.105, released in April 2012, the name of the project was changed from ''PolicyKit'' to ''polkit'' to emphasize that the system component was rewritten and that the API had changed, breaking backward compatibility. Fedora became the first distribution to include PolicyKit, and it has since been used in other distributions, including Ubuntu since version 8.04 and openSUSE since version 10.3. Some distributions, like Fedora, have already switched to the rewritten polkit. It is also possibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front End And Back End
In software engineering, the terms frontend and backend (or sometimes referred to as back end or back-end) refer to the separation of concerns between the presentation layer (''frontend''), and the data access layer (''backend'') of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself. Introduction In software architecture, there may be many layers between the hardware and end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. In telecommunication, the ''front'' can be considered a device or service, while the ''back'' is the infrastructure that supports provision of service. A rule of thumb is that the client-side (or "frontend") is any com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
