Wings: failed to initialize the sftp server error=ssh: no key found

Current Behavior

Hell,

as suggested on installation instructions I am running wings for the first time after config was copied to /etc/pterodactyl/config.yaml. This is what I get:

root@ptero:~# wings --debug

This happens on dedicated Debian system:

root@ptero:~# uname -a
Linux ptero 6.1.0-23-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.99-1 (2024-07-15) x86_64 GNU/Linux

I have found the source code where the issue is happening, but I am not able to find exact line because the binary has its symbols stripped. I would like to ask you for help identifying a command to isolate the issue so I can continue finding the root cause.

Thank you, m.

Is there an existing issue for this?

• [X] I have searched the existing issues before opening this issue.
• [X] I have provided all relevant details, including the specific game and Docker images I am using if this issue is related to running a server.
• [X] I have checked in the Discord server and believe this is a bug with the software, and not a configuration issue with my specific system.

Hi, so i could reproduce this, and i also know how to fix this.

The issue seems that wings have issues creating / finding the correct keys so the function works but it also doesn't, so it definitely a bug that needs to be checked out.

Tested on Ubuntu 24.04

To fix the issue

Create a new key using this command

ssh-keygen -t ed25519

and set the location of the file to be

/var/lib/pterodactyl/volumes/.sftp/id_ed25519

NOTE: If you are asked if you want to overwrite say yes, and also just leave the passphrase empty.

I confirm the key was an empty file:

root@ptero:/var/lib/pterodactyl/volumes/.sftp# cat id_ed25519 
root@ptero:/var/lib/pterodactyl/volumes/.sftp#

Now the wings runs.

Thank you, m.

Do you know what the file was empty? In other words could we fix it in the code?

Sadly i dont, it might be a case of the go function not running properly or write permissions might be wrong.
