Red Hat SummitChapter 1. Software management tools in Red Hat Enterprise Linux 8
In Red Hat Enterprise Linux (RHEL) 8, use YUM to manage software. YUM is based on the DNF technology, which adds support for modular features.
Upstream documentation identifies the technology as DNF, and the tool is referred to as DNF. As a result, some output returned by the new YUM tool in RHEL 8 mentions DNF.
Although YUM is based on DNF, it is compatible with YUM used in RHEL 7. For software installation, the yum command and most of its options work the same way in RHEL 8 as they did in RHEL 7.
Selected YUM plug-ins and utilities have been ported to the new DNF back end and can be installed under the same names as in RHEL 7. Packages also provide compatibility symlinks. Therefore, you can find binaries, configuration files, and directories in usual locations.
The legacy Python API provided by YUM in RHEL 7 is no longer available. You can migrate your plug-ins and scripts to the new DNF Python API provided by YUM in RHEL 8. For more information, see DNF API Reference.
