Chapter 1. Software management tools in Red Hat Enterprise Linux 9
In Red Hat Enterprise Linux 9, software installation is ensured by the DNF tool. Red Hat continues to support the usage of the
yum term for consistency with previous major versions of RHEL. If you type
yum instead of
dnf, the command works as expected because both are aliases for compatibility.
Although RHEL 8 and RHEL 9 are based on DNF, they are compatible with YUM used in RHEL 7.
