I tried using tmate for the first time today, with the suggested minimal configuration:

    - name: Setup tmate session
      uses: mxschmitt/action-tmate@v3

On all my runners, tmate simply went into an infinite loop (and blocked progress on the remaining workflow steps). The output looks like this:

[continues indefinitely, until I cancel the workflow]

In this case, the action was running on a standard ubuntu-22.04 instance.

Thanks!

That's exactly what it's supposed to do. It stalls the job so you can work, and spits out the command you can use to access the runner now. In your case, you'd run:

ssh [email protected]

Thanks for the reply! Yes, this wasn't clear at first, but I eventually figured it out.

tmate team: You might consider printing a log message such as "Waiting for SSH client to connect ..." alongside the existing messages. This would make it crystal clear that tmate is pausing execution while waiting to hear from the client.

Thanks!
