🗒 Tutorial

Details

Oracle Linux provides the dnf utility, based on Dandified Yum (DNF), as the client software for installing and managing system packages. These packages can come from the Unbreakable Linux Network (ULN) or an Oracle Linux yum server. Software packages are installed on a system using standard dnf commands and depend on the system having enabled the appropriate ULN channel subscriptions or yum repositories. While installing or upgrading packages, dnf automatically handles package dependencies and requirements.

DNF significantly improves functionality and performance and brings many new features, including modular content and a more stable and documented API, compared to the traditional’ yum’ command.
