Error: HOME is not defined

[gilShin]

I start my hosted runner and when it gets to the ssh-key-action step, I get the error message in the subject. When I ssh into the runner and executes: echo $HOME, I get /home/ubuntu as expected

What am I missing here?

I've got the same on a self-hosted runner.

My workaround:

- run: mkdir -p /home/runner && chmod -R 777 /home/runner
- run: echo "HOME=/home/runner" >> $GITHUB_ENV

Hi, @gilShin @chekalsky Thank you for your report, and sorry for late response.

I start my hosted runner and when it gets to the ssh-key-action step, I get the error message in the subject.

It looks strange... :thinking: I found issue https://github.com/actions/runner/issues/1864, you might want to read it!

same issue here, self-hosted ubuntu-latest

I've fixed this issue by adding an env to the step.

      - name: Install SSH key
        uses: shimataro/ssh-key-action@v2
        env:
          HOME: /root
        with:
          .....

I only have this issue on a custom runner, not on the default Ubuntu runners provided by GitHub.
