Fortunately, this is a relatively frequent problem that may be readily resolved by trying a few easy fixes.

In addition to the systemd tool, Linux uses the systemctl command to control and examine system management.

It also oversees the appropriate start-up of things like a system activity log.

Overall, this program serves as the primary administration tool for most Linux-based operating systems.

Many older Linux versions utilize SysV init rather than systemd.

However, this resulted in the systemctl: command not found error.

Fix systemctl: command not found Error.

Fortunately, this is achievable, and here is how you could do so.

The service command aids in executing the SystemV init script used by earlier Linux operating systems.

If you dont want to roll out the Systemd program, you may use this to complete your task.

In a nutshell, the systemctl and service commands have the same functionality.

The only difference is their compatibility with the command utilities accountable for all Linux-oriented systems proper functioning.

Let us try executing the same command with the service command while initiating the ufw service.

Ensure Systemd Package is Installed

A simple installation of the systemd package will sometimes handle the problem.

The most likely cause of this issue is using an outdated or older version of the Linux distribution.

Many earlier versions rely on the SysV init tool rather than the systemd utility.

The systemctl command not found error is anticipated if you are not utilizing the systemd.

Thats how easy and uncomplicated it is.

How do you see if the systemd package is installed on your PC?

This is due to the unsupported behavior of the systemd command on earlier Linux operating systems.

If the system tool is not installed but supported by your Linux version, you should consider installing it.
