Downloading virtualmin-release-latest.noarch.rpm [ERROR] Failed with error: 22

Hi i try install but have error 22 .I post log :
[root@localhost ~]# ./install.sh
Perl was not found on your system - Virtualmin requires it to run.
Attempting to install it now.

Welcome to the Virtualmin GPL installer, version 6.0.12

This script must be run on a freshly installed supported OS. It does not
perform updates or upgrades (use your system package manager) or license
changes (use the “virtualmin change-license” command).

The systems currently supported by install.sh are:

CentOS/RHEL Linux 6 and 7 on x86_64
Debian 7, 8, and 9, on i386 and amd64
Ubuntu 14.04 LTS and 16.04 LTS on i386 and amd64

If your OS/version/arch is not listed, installation will fail. More
details about the systems supported by the script can be found here:

https://www.virtualmin.com/os-support

The selected package bundle is LAMP and the size of install is
full. It will require up to 650 MB of disk space.

Exit and re-run this script with --help flag to see available options.

Continue? (y/n) y
