Github action -> SSH connection trouble

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

Solution

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
