Recently when I use your plugin with GameCi

name: Accessing private repos
runs-on: ubuntu-latest
steps:
  - uses: actions/checkout@v2
  - uses: webfactory/ssh-agent@v0.8.0
    with:
      ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
  - uses: game-ci/unity-builder@v2
    with:
      sshAgent: ${{ env.SSH_AUTH_SOCK }}

I get this error :

Error when executing git command. ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
    Host key verification failed.
    fatal: Could not read from remote repository.

    Please make sure you have the correct access rights
    and the repository exists.

I know GitHub recently changed its public key, but even after updating your action I'm still getting errors, How can I fix this?

@uchar maybe the information in #171 (comment) helps?

@uchar maybe the information in #171 (comment) helps?

I'm a little lost here , since game-ci/unity-builder is a docker image, do they have to add it inside their docker image? I can't find a way to do it manually

I haven't used Docker-based build images so far, I don't know...

The only explanation would be when this action webfactory/ssh-agent is run inside the Docker container. Is that the case?

If it is run outside (on the runner), then the known_hosts entry should already be present.

@mpdude Yes I think it is running inside the docker
I fixed the problem by adding the GitHub to known hosts manually :

- name: "Add GitHub to the SSH known hosts file"
  run: |
    mkdir -p -m 0700 /home/runner/.ssh
    curl --silent https://api.github.com/meta  | jq --raw-output '"github.com "+.ssh_keys[]' >> /home/runner/.ssh/known_hosts
    chmod 600 /home/runner/.ssh/known_hosts
