Hi @SimonC-Audigent,
ubuntu-latest image which references ubuntu-24.04 does not have sbt pre-installed anymore.
Here, is the list of softwares installed in this image.

Please feel free to use any of the two below options to fix your issue -

1. change the runner label of the workflow to ubuntu-22.04 where sbt is available.
   or
2. Use the community provided sbt installation action

     - name: Install sbt 
       uses: sbt/setup-sbt@v1
