Building error on github actions

Help
1

Hi folks, I have been building my jekyll site on github actions for a while. Last week, the OS of github actions updated from Ubuntu 22.04 to 24.04. And I’ve receive building errors since then. Can anyone help me with it?

Here is the error message:

The current runner (ubuntu-24.04-x64) 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).
In such a case, you should install Ruby in the $RUNNER_TOOL_CACHE yourself, for example using https://github.com/rbenv/ruby-build
You can take inspiration from this workflow for more details: https://github.com/ruby/ruby-builder/blob/master/.github/workflows/build.yml
$ ruby-build 3.1.4 /opt/hostedtoolcache/Ruby/3.1.4/x64
Once that completes successfully, mark it as complete with:
$ touch /opt/hostedtoolcache/Ruby/3.1.4/x64.complete
It is your responsibility to ensure installing Ruby like that is not done in parallel.

And here is the yml building script:

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

It’s temporarily solved by modifying a line in building script from runs-on: ubuntu-latest to runs-on: ubuntu-22.04.

I’ll leave the post as is just in case anyone else encountered the same problem.

I think your problem would be solved by using a more recent version of setup-ruby, see this issue:
