auth with rsa privacy key. but have error: SSHAuthFailError(All authentication methods failed)
this is log:

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 [email protected] -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.
The same problem as you, "All authentication methods failed" And FileZilla works fine.
I also encountered the same problem. Is there any solution now?
@falrom were you able to modify this package to connect with your ssh-rsa type?
Update: In case anyone is interested, rsa authentication was deprecated and replaced with rsa-sha2-256 in this commit. You can revert to version 2.7.0 before this was merged.
