This was required due to Fedora's transition from Python 2 to Python 3, which isn't supported by YUM. Ī rewrite of YUM named DNF replaced YUM as the default package manager in Fedora 22. GUI-based wrappers such as YUM Extender (yumex) also exist, and has been adopted for Fedora Linux until version 22. YUM is implemented as libraries in the Python programming language, with a small set of programs that provide a command-line interface. Under the hood, YUM depends on RPM, which is a packaging standard for digital distribution of software, which automatically uses hashes and digital signatures to verify the authorship and integrity of said software unlike some app stores, which serve a similar function, neither YUM nor RPM provide built-in support for proprietary restrictions on copying of packages by end-users. Like the Advanced Package Tool (APT) from Debian, YUM works with software repositories (collections of packages), which can be accessed locally or over a network connection.
YUM allows for automatic updates and package and dependency management on RPM-based distributions.
Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality. The Yellowdog Updater, Modified ( YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager.
