I try to use FileZilla to connect, it's fine.
So I don't know where I'm going wrong

The same problem as you, "All authentication methods failed"
And FileZilla works fine.

same error, any solution?
same pem file works with filezilla and node app using https://github.com/mscdex/ssh2

I can use the same key file to connect on FileZilla, or directly using SSH:

ssh root@10.64.20.141 -p 1922 -i /home/username/id_rsa -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa

My dart code here:

import 'dart:convert';
import 'dart:io';
import 'dart:async';

import 'package:dartssh2/dartssh2.dart';

Future<void> main() async {
  final client = SSHClient(
    await SSHSocket.connect('10.64.20.141', 1922),
    username: 'root',
    identities: [
      // A single private key file may contain multiple keys.
      ...SSHKeyPair.fromPem(await File('/home/username/id_rsa').readAsString())
    ],
    printDebug: print,
    printTrace: print,
  );
  print(utf8.decode(await client.run("ls -lah /home")));
  client.close();

  return;
}

Is there any way to specify HostKeyAlgorithms like in the SSH command? I tried modifying the values of the algorithms list, but it doesn't seem to work.

It looks like -o PubkeyAcceptedKeyTypes=+ssh-rsa did the trick.

The same problem as you, "All authentication methods failed" And FileZilla works fine.

I also encountered the same problem. Is there any solution now?
