There is indeed no content.

I want to configure the state to perform a certain action if curl returns an error.

There is a Salt state called http which can query a URL and return the status. Using this (instead of curl) we can check for the status code(s) (200, 201, etc.), as well as matching text. Then we can use requisites to run subsequent states depending on the success/failure of the http.query.

Example:

I have added a check for status code of 200, you can omit - status: 200 if you don't care about the status code.

The requisites that we mention, such as require, watch, etc. should be references to other states that are "scheduled" to run on the targets.

About watch

Even though the path is created by installing the "realvnc" package, there is no Salt state to handle the path. That is why it is showing the error.

Quoting from documentation for watch:

A watch requisite is used to add additional behavior when there are changes in other states.

So if you want to watch on a file, then there should be a state that "handles" the file using the file module.

About require

Also, while specifying require you are referring to pkg module, so Saltstack would look for pkg.installed for realvnc. Whereas you are using chocolatey.installed.

So with below modifications it should work fine.

The library that you are using might expect to get the public key in PEM format i.e. enclosed between -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY-----. So you would have to change your pubkey to :
