Github action -> SSH connection trouble – Ubuntu

i have an issue with my github action and i can’t connect with ssh i did this :

  • Create an ssh key with user adam

  • Copy the public key into /root/.ssh/authorized_keys

  • Create a secret in github with the public key

  • Create a script.sh into /home/adam/

  • chmod 600 .ssh directory

But i got this error :

Run ssh -o StrictHostKeyChecking=no
Warning: Identity file /home/adam/.ssh/id_rsa not accessible: No such file or directory.
Warning: Permanently added ‘my Ip’ (ED25519) to the list of known hosts.
adam@my Ip: Permission denied (publickey,password,keyboard-interactive).
Error: Process completed with exit code 255.

This is my code :

        name: Run script on VPS
on:
  push:
    branches: [master]
jobs:
  run-script:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Run script
        env:
          SSH_PRIVATE_KEY: ${{ secrets.VPS_SSH_PUBLIC_KEY }}
        run: |
          ssh -o StrictHostKeyChecking=no 
              -o PasswordAuthentication=no 
              -i /home/adam/.ssh/id_rsa 
              adam@myip 
              "bash /home/adam/script.sh"

Can someone help me fix this ?

  • tried to verify if the path to the id_rsa and id_rsa.pub is correct
  • saw both files were there and with the good key inside
  • tried reacreate ssh key multiples time
  • tried different way to access ssh
  • verify conf open ssh accept rsa and add this line CASignatureAlgorithms +ssh-rsa
  • restart service ssh

    thank you for your answers I don't know exactly what was the issue but i think it was related with the ssh key

    I fixed my code by using password that is store in secret of github instead of ssh key

      name: Deploy 🚀
    on:
      push:
        branches:
          - master
    jobs:
      deploy:
        runs-on: ubuntu-latest
        steps:
          - name: Checkout code
            uses: actions/checkout@v2
          - name: Install Node.js
            uses: actions/setup-node@v2
            with:
              node-version: '16.x'
          - name: Install dependencies
            run: npm install
          - name: Build project
            run: npm run build
          - name: SSH Deploy
            run: |
              sshpass -p ${{ secrets.PSWD }} ssh -o StrictHostKeyChecking=no -p 22 ${{ secrets.USER}}@${{ secrets.VPS_IP }} 'cd /home/adam && ./deploy.sh'
            env:
              SSHPASS: ${{ secrets.PSWD }}

    Copy the public key into /root/.ssh/authorized_keys

    That is on the remote target server you want to SSH to.

    And it means you want to SSH to as root: root@remoteServer:....
    Not as adam@...

    Instead of relying on local path which does not exist on GitHub runner (unless maybe self-hosted), you might want to use the GitHub Action "appleboy/ssh-action"

      - name: ssh key passphrase
    uses: appleboy/[email protected]
    with:
      host: ${{ secrets.HOST }}
      username: ${{ secrets.USERNAME }}
      key: ${{ secrets.KEY }}
      port: ${{ secrets.PORT }}
      passphrase: ${{ secrets.PASSPHRASE }}
      script: |
        whoami
        ls -al

    Remove the passphrase: ${{ secrets.PASSPHRASE }} line if your SSH private key is not passphrase protected.

    That way, you do not need to create .ssh/ folder with the right permission. That action takes care of all that for you.
