```sh
act

Describe issue

Reports, erroneously that the current runner "was detected as self-hosted".

Using runs-on: ubuntu-latest produces same output.

However, https://github.com/actions/runner-images indicates ubuntu-latest or ubuntu-22.04 are GH supported runner images.

Relevant log output

::error::The current runner (ubuntu-22.04-arm64) was detected as self-hosted because the platform does not match a GitHub-hosted runner image (or that image is deprecated and no longer supported).%0AIn such a case, you should install Ruby in the $RUNNER_TOOL_CACHE yourself, for example using https://github.com/rbenv/ruby-build%0AYou can take inspiration from this workflow for more details: https://github.com/ruby/ruby-builder/blob/master/.github/workflows/build.yml%0A$ ruby-build 3.2.2 /opt/hostedtoolcache/Ruby/3.2.2/arm64%0AOnce that completes successfully, mark it as complete with:%0A$ touch /opt/hostedtoolcache/Ruby/3.2.2/arm64.complete%0AIt is your responsibility to ensure installing Ruby like that is not done in parallel.%0A

Appending --container-architecture linux/amd64 fixes this issue. Thanks!
