The Ubuntu repository package is a repository of some data, in this case, programs. Linux distributions have official and unofficial repositories. Most of them offer free software installation.
Repository and software
Users of Windows or Mac OS are used to the fact that the software comes in the form of installation files. But programs for Linux Ubuntu 18 04 are .deb packages that contain programs and the necessary libraries. They are stored in the repositories to which the user connects before installation.
This provides a decentralized method for installing or uninstalling software. Simplifies uploading updates, finding the right programs and add-ons. The installed distribution contains all the necessary repositories with a large variety of software. Installing programs from repositories is equivalent to a user downloading a package from the Internet or compiling a program from source.
Search and configuration of repositories in Ubuntu is carried out using special utilities, for example, Synaptic. This is a GUI program for managing packages in Ubuntu-like Linux distributions. Combines the capabilities of a console system and the convenience of a graphical interface. Allows you to install, uninstall, configure, update packages.
Types of software
Programs from the Ubuntu repository list are divided into four sections. Each group is distinguished by availability and license capabilities. Some of them are supported by Canonical, the creator of Linux.
Distributed in this way:
- main - free, supported by Canonical;
- restricted - proprietary, supported by Canonical;
- universe - free, not supported by Canonical;
- multiverse - proprietary, not supported by Canonical.
