ttyを持たないユーザー(私のapacheサーバーを実行しているユーザー)からsshを(キー認証を使用して)呼び出して単一のコマンドを実行しようとしていますが、次の結果が得られます。

sshを呼び出すと、-tフラグが設定されます。キーにはパスフレーズがないため、入力の必要性は抑制されますが、明らかにそうではありません。sshが/ dev / ttyを開こうとしないようにするにはどうすればよいですか?
編集:コードタグが機能していませんか?
Edit2:フルsshコマンド:
ssh -i nonpublic/id_rsa -l username -p 54367 -t -v username@localhost /home/username/minecraftserver/Scripts/start 2>&1
ユーザー名を「username」に置き換えました。
Edit3:rootと同じキーを使用してssh-ingを試行し、次の結果を得ました。

パスフレーズは必要ないはずですが、パスフレーズの入力を求められます。さらに、WindowsマシンでPuTTYを使用してSSHでキーを使用しても問題なく、パスフレーズの入力を求められません。
Edit4:私はサーバーをapacheユーザーのknown_hostsに追加し、今これを取得します:

また、これはknown_hostsの内容です:
[localhost]:54367 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBILr7jLp5CeYfyrCroaDjkaWgDHXRrQD+G8Fz/CQOY1PcluUFTkrN447bXmC6R27LOClE+RPaveYb4MOlObpGGE=
ecdsaと表示されるのはなぜですか?これは、RSAキーです。
Edit5:解決しました。問題は、キーペアがPuTTYによって生成され、OpenSSHと互換性のない形式で秘密キーを書き込むことでした。コメントでcjcによって提供されるソリューション。
-tですか?
