ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

This is my workflow file
what i am trying to do with this action is on pushing to master

• create a docker image
• push the docker image to docker hub
• ssh into my AWS EC2 server
• run a set of instruction to update the docker image

on:
  push:
    branches: [master]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: docker login
      env:
        DOCKER_USER: ${{ secrets.DOCKER_USER }}
        DOCKER_PASSWORD: ${{ secrets.DOCKER_PASSWORD }}
      run: |
        echo $DOCKER_PASSWORD | docker login -u $DOCKER_USER --password-stdin
    - name: Build the React Docker Image
      run: |
        docker build . --file Dockerfile --tag noobmaster147/feedachild-frontend
    - name: Docker push 
      run: |
        docker push noobmaster147/feedachild-frontend
    - name: Deploy
      uses: appleboy/ssh-action@master
      with:
        host: ${{ secrets.HOST }}
        username: ${{ secrets.USERNAME }}
        key: ${{ secrets.KEY }}
        port: ${{ secrets.PORT }}
        script: |
          whoami
          pwd
          ls -la
          docker-compose down
          docker-compose pull
          docker-compose up --build -d

I am stuck with this issue for hours now.

the pem file that I am using was generated by aws, in the process of creating an instance

this is the command I use to ssh from my laptop ssh -i ~/Documents/feedachild.pem ubuntu@ec2-*-**-***-***.us-east-2.compute.amazonaws.com

therefore the secrets I added were
HOST => ec2-*-**-***-***.us-east-2.compute.amazonaws.com
PORT => 22
USERNAME => ubuntu
KEY => pasted the RSA Key as it is

I am getting same error how Can I resolve this Issue "ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain"

@Yaqoob-Aslam Do you refer to https://github.com/appleboy/ssh-action#setting-up-a-ssh-key guide?

[Dev-El-badry]

check permissions of authorized_key file and private key file

• change permission authorized_key file
  chmod 640 .ssh/authorized_key

• change permission .ssh file
  chmod 700 .ssh/private_key

[shylock-wu]

Is this the file in the aws server?

[nhastor1]

In case of administrative user on windows, you need to add your public key into file named administrators_authorized_keys in C:\ProgramData\ssh\.

[ct123-cmd]

You only need to authorize your key

cat ~/.ssh/id_rsa.pub >> authorized_key

[syntaxlexx]

You only need to authorize your key

cat ~/.ssh/id_rsa.pub >> authorized_key

It's funny how something as trivial as this can keep one awake at night! Kuddos!
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

[sugurugojow]

@syntaxlexx where do i have to put this in my local or my ec2 instance ?

[ct123-cmd]

This is just a way to authorize your key when connecting using SSH, it depends on your requirements.
what is your purpose? building a CI/CD pipeline or a code pipeline from local to GitHub or somewhere?

[sugurugojow]

for ci/cd pipeline

[ct123-cmd]

This is something needs to check from start to end, but what I can see in your error logs, you did something wrong with your key files, and that's why you are not able to push the code, You can start with a new key files there, make sure you give right permissions and proper approach for that

check permissions of authorized_key file and private key file

• change permission authorized_key file
  chmod 640 .ssh/authorized_key
• change permission .ssh file
  chmod 700 .ssh/private_key

Is this in the EC2 instance or my local machine, kindly be more explicit

This worked for me!!!

Working... thanks.

This command must be past into EC2 o Droplet (digitalOcean)

[EdvardasP]

For me the problem was with permissions on authorized_keys file. It had 664, changing to 600 helped and deployment works again.

ssh is different to sshd. Make sure you have set PasswordAuthentication to yes in the SSHD file, and restarted the sshd service.

[ucodefusion]

Step 1

Add this values to github ,

If you not sure what it is
SERVER_IP your server ip ping your_server_domain.com
SERVER_USER AWS EC2, DigitalOcean, or Azure, the default username will be ubuntu. If you're using a different or a custom setup, the default user might be root, ec2-user (for Amazon Linux),
SSH_PRIVATE_KEY your server private key cat ~/.ssh/id_rsa

Step 2

cat ~/.ssh/id_rsa.pub >> authorized_key

Step 3 Run your pipeline

when I access cPanel using ssh client, I got this error.
How to handle this error?
