![]() ![]() Brown at Duke published documentation for YUM. Vidal continued to contribute to YUM until his death in a Durham, North Carolina bicycle accident on 8 July 2013. Īs a full rewrite of YUP, YUM evolved primarily to update and manage Red Hat Linux systems used at the Duke University Department of Physics by Seth Vidal and Michael Stenner. The original package manager, Yellowdog UPdater (YUP) was developed in 1999-2001 by Dan Burcaw, Bryan Stillwell, Stephen Edie, and Troy Bengegerdes at Terra Soft Solutions (under the leadership of then CEO Kai Staats) as a back-end engine for a graphical installer of Yellow Dog Linux. DNF also improves on YUM in several ways - improved performance, better resolution of dependency conflicts, and easier integration with other software applications. 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.
