Failed to checkout submodule

See original GitHub issue

Trying to checkout a repo with single submodule in it.

both repos are part of the same organization
both repos are private
organization requires sso and ssh keys to access repos

the workflow fails at the following

steps:
  - name: Checkout
     uses: actions/checkout@v2
     with:
       ref: develop
       ssh-key: ${{ secrets.SSH_KEY }}
       submodules: true

the failure message

Load key "/home/runner/work/_temp/dc2e5ba9-c8ee-424c-a39b-a15919ec6f72": invalid format
git@github.com: Permission denied (publickey).
##[error]fatal: Could not read from remote repository.

Not sure if I miss coded the flow, but it’s unclear why I’m not able to access the remote repo with the SSH_KEY

@samuelematias and you did not provide an ssh-key to the checkout action? Wouldn’t that have it use an https url for checkout?

Is secrets.SSH_KEY the private key? Is it protected by a passphrase?

For that error, saw some interesting troubleshooting here throughout the various answers/comments. Especially the ones about different versions of OpenSSL and “Perhaps it has accidentally enabled FIPS mode and refuses any algorithms except those part of its original FIPS validation”. It makes me wonder whether you are using a job container (may have an insufficient version OpenSSL), if so have you tried on the host machine instead (e.g. runs-on: ubuntu-latest)?
