All configured authentication methods failed

Hi,
I reinstalled my server today (I upgraded it to 22.04) and when I wanted to reconfigure an automatic "git pull" on it with github actions, I got the following error :

Here is my workflow file :

    steps:
      - name: pull palgania server
        uses: garygrossgarten/github-action-ssh@release
        with:
          command: pull

        env:
          CI: true

The RSA keys which I use work correctly, I can connect my server through them.
I don't remember any issue the first time I configured it.
I did not try password connection but I can't use it, as it's a password-less login (RSA keys only).

Did you figure it out? I have the exact same problem.

[nimbomx]

Same here, any solution?

I did not find any solution with this action. I just pull manually for now. If you absolutely need something to pull automatically, you should maybe consider using an FTP solution as FTP-Deploy.

Hello.
I found something that could fix this issue : appleboy/ssh-action#157 (comment)

@mcmatthevan thank you for the solution this works for me

@garygrossgarten Is there any chance that you upgrade your action beyond the necessary work-around with the ssh config "PubkeyAcceptedKeyTypes=+ssh-rsa" to be set?

I don't fully understand the issue, GPT says:

Setting PubkeyAcceptedKeyTypes=+ssh-rsa in your SSH configuration allows the use of the ssh-rsa key algorithm for public key authentication. This has significant security implications:

Security Impact: Weak Cryptography
ssh-rsa relies on SHA-1 for signing, which is considered weak due to collision attacks (where different inputs produce the same hash).
Modern cryptographic research has shown that SHA-1 can be broken with sufficient computational power.
