Input.GetButtonDown("Jump"); in Unity does not work for space key

I know this question has been asked and answered before but in my case, the answers just won't cut it. No answer I have looked at before was able to solve this and even in the Unity forum, I couldn't find useful information. In Unity, I'm trying to build a 2D game, nothing big.

I am trying to set up my movement-script and horizontal movement worked like a charm. But jumping does not work, at least when the button is assigned to Space. Here is my code so far:

void Update() {
    if (Input.GetButtonDown("Jump")) {
        Debug.Log("Jump!");
        rigidBody.velocity = new Vector2(rigidBody.velocity.x, jumpSpeed);
    }
}

It is -as you can tell- really simple. I tried to assign another key to Jump. With the E button everything went fine and my character jumped. But when using the Space, it did not work. Here's an image of my input manager:

Notice that I don't have a second Jump option configured. This was where I used the E key.

(I am using Linux Mint Tricia 19.3 if that gives any further information)

As an alternative you could use if (Input.GetKeyDown(KeyCode.Space)) maybe the issue is how the Jump button is set up, but nothing stands out to me.

I believe you can use GetKeyDown and KeyCode to solve your problem. Your code can be modified to use these functions. I have improved your code down below. Just make sure that KeyCode.Space is not assigned to any other key.

void Update() {
    if (Input.GetKeyDown(KeyCode.Space)) {
        Debug.Log("Jump!");
        rigidBody.velocity = new Vector2(rigidBody.velocity.x, jumpSpeed);
    }
}

I also have some scripting docs for you:
