Git permissions issues when running on self hosted runner

[yangcheng]

I try to use this action on ec2 with self host runner, eventual failure on

by comparing the log to default runner, I suspect it's related to git ownership issue. I had the following warning in log.

Run flutter doctor -v
fatal: detected dubious ownership in repository at '/actions-runner/_work/_tool/flutter/stable-3.10.0-x64'
To add an exception for this directory, call:

git config --global --add safe.directory /actions-runner/_work/_tool/flutter/stable-3.[10]

I tried to add git config call both before and after use action without luck

 do-the-job:
    name: Do the job on the runner
    needs: start-runner # required to start the main job when the runner is ready
    runs-on: ${{ needs.start-runner.outputs.label }} # run the job on the newly created runner
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          distribution: 'corretto'
          java-version: '11'
      - name: fix flutter git permission
        run: git config --global --add safe.directory /actions-runner/_work/_tool/flutter/stable-3.10.0-x64
        env:
          HOME: ${{ github.workspace }}
  
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: "3.10.0"
          channel: "stable"
      
      - run: flutter doctor -v

 do-the-job:
    name: Do the job on the runner
    needs: start-runner # required to start the main job when the runner is ready
    runs-on: ${{ needs.start-runner.outputs.label }} # run the job on the newly created runner
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          distribution: 'corretto'
          java-version: '11'
      - name: fix flutter git permission  
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: "3.10.0"
          channel: "stable"
       - run: git config --global --add safe.directory /actions-runner/_work/_tool/flutter/stable-3.10.0-x64
        env:
          HOME: ${{ github.workspace }}
      - run: flutter doctor -v

both fail ,. if i just call git config without setting home, it will fail on $HOME not set.

What's the correct way to use this action on self hosted runner? I think it's related to the git things but can;t figure out how to resolve it.

Thanks !

The following is caused by incorrect ownership/permissions for the user that setup the worker, I came across this when I realised one of my workers was running as root and then I changed it to run as a user, this error was then thrown, the easiest fix is to remove the bad folders and let GitHub fix when it does the checkout for that folder.

fatal: detected dubious ownership in repository at '/actions-runner/_work/_tool/flutter/stable-3.10.0-x64'

I also got this but with GitHub's own runner, https://github.com/ExpidusOS/file-manager/actions/runs/5097074866/jobs/9163360990.

If you are using act to run locally I managed to fix the issue by using a docker that uses a normal user called "runner" instead of root. https://github.com/catthehacker/docker_images

runs-on: ubuntu-latest

and

act -P ubuntu-latest=ghcr.io/catthehacker/ubuntu:runner-latest
