Broken on Github's ubuntu-latest runner

[theCalcaholic]

Behaviour

Steps to reproduce this issue

1. Create a workflow with the following job:

   jobs:
     setup-qemu:
       runs-on: ubuntu-latest # or ubuntu-22.04
       steps:
         - name: setup qemu
           uses: docker/setup-buildx-action@v2

2. Run the workflow

Expected behaviour

setup-qemu-action should setup binfmt and qemu successfully.

Actual behaviour

The job fails with:

> Run docker/setup-qemu-action@v2
> Docker info
> Pulling binfmt Docker image
> Image info
> Installing QEMU static binaries
  /usr/bin/docker run --rm --privileged tonistiigi/binfmt:latest --install all

Looking at your docker info output, there's something odd with your runner compared to a public one: https://github.com/nextcloud/nextcloudpi/actions/runs/5529886024/jobs/10088602638#step:3:44

Looks like ubuntu-latest is not a public runner in your organization but a self-hosted one.

Closing since that does not seem an issue with the action but runner configuration.

[theCalcaholic]

@crazy-max Actually, I'm relatively sure that I'm using the official github hosted runners.
What makes you think otherwise? 🤔

[crazy-max]

Actually I encounter a similar issue on another repo where ubuntu-latest runner was not consistent: tonistiigi/xx#116

Looks like the latest runner image is not synced properly across their infra:

One is 20230710.1.0 and the other 20230517.1 while being part of the same matrix using ubuntu-latest. So I'm pretty confident this is a GitHub runner issue that should be reported in https://github.com/actions/runner-images. (fyi @cpuguy83)

@theCalcaholic In your case you're not using a public runner from what I see though: https://github.com/nextcloud/nextcloudpi/actions/runs/5529886024/jobs/10088602638#step:3:44

[theCalcaholic]

I see, thank you.
Looks, like this is due to GH organization policy - I didn't even realize that.
(I don't actually belong to the Nextcloud company which owns the Github org, but am maintaining a community project within their GH namespace).
