The "Tutorial: Get started with Go" recommends the wrong package version of rsc.io/quote. Using the standard 1.5.2 version results in TLS handshake errors. Switching to v4 gives the expected results.

Raised this as a separate issue as that issue is in regards to the wording surrounding searching for the package. This issue is in regards to the code now completely failing to work as it is written in the tutorial.

Code

Original Code:

package main

import "fmt"

import "rsc.io/quote"

func main() {
    fmt.Println(quote.Go())
}

Changed Code:

package main

import "fmt"

import "rsc.io/quote/v4"

func main() {
    fmt.Println(quote.Go())
}

Go Version

go version go1.20.2 linux/amd64

OS

Ubuntu 20.04.6 LTS running under WSL

What did you do?

Followed the tutorial as it was written. Adding /v4 to the import and rerunning mod tidy corrected the error.

What did you expect to see?

Mod tidy should have executed with downloading the module.

What did you see instead?

Mod tidy error-ed out a TLS handshake.
