iOSゲーム開発 – トラブルシューティング

エラー内容としてはMacにリモートで接続するための秘密鍵のパーミッションが正しくないと怒られています。

「Permission denied (publickey,password,keyboard-interactive).」の原因はいくつか考えられますが、その中で私がハマったものを紹介します。

WinからMacへリモートビルドを行うために、事前に[プロジェクト設定] -> [iOS] -> [Build] -> [Remote Build Options] にてリモートビルドのセットアップを行いますが、[新規SSHキーを生成]する際に、リモート先のMacのOpenSSHのssh-keygenを使用して秘密鍵を生成します。
しかしMacのOSバージョンが 10.14 Mojave 以上の場合、OpenSSHのバージョンが7.8になり、ssh-keygenで使用する秘密鍵のデフォルト形式がPEM形式からOpenSSH形式に変更されたようで、これはUE4が使用しているDeltaCopyのバージョン5.1には対応していません。このため、上記のエラーが発生します。
（参考：OpenSSH 7.8p1 での変更点のまとめ）
これは[新規SSHキーを生成]をMojave以前のOSでしていても、その後にMojaveにアップデートして新たに[新規SSHキーを生成]をし直してしまうと発生するはずです。

この不具合はUE4の4.21.1にて修正済みです。もし発生する場合は、4.21.1以降のバージョンで再度[新規SSHキーを生成]を実行してください。

記録として手動での修正方法を下記に残しておきます。

根本対応としてはUE4付属のDeltaCopyで使用しているOpenSSHをOpenSSH形式の秘密鍵に対応したバージョンまで引き上げることですが、とりあえず簡単にできる暫定対応として、Mac側にssh-keygenをリクエストする際に、オプションをつけてPEM形式で秘密鍵を生成してもらうようにします。

UE4の下記のフォルダにある MakeAndInstallSSHKey.bat を編集します。
C:\Program Files\Epic Games\UE_4.xx\Engine\Build\BatchFiles\MakeAndInstallSSHKey.bat

%SSH% -p %SSHPORT% "%USER%@%MACHINE%" "if [[ ! -e .ssh ]]; then mkdir .ssh; fi && cd .ssh && if [[ -e authorized_keys ]]; then cp -f authorized_keys authorized_keys_UEBackup; fi && ssh-keygen -t rsa -f RemoteToolChain -m PEM && mv -f RemoteToolChain.pub RemoteToolChainPublic.key && mv -f RemoteToolChain RemoteToolChainPrivate.key && cat RemoteToolChainPublic.key >> authorized_keys";

36行目の後ろの方に ssh-keygen を呼び出している箇所がありますので、引数に -m PEM というオプションを追記します。
その後、改めて[プロジェクト設定]から[新規SSHキーを生成]を実行して、PEM形式の秘密鍵を作り直すことで、このエラーは解消されます。

UE4の4.21から、秘密鍵周りのエラーがこの文言に集約されてしまったようです。
上記のエラー1、エラー2の原因が当てはまる可能性が高いので、そちらを試してみてください。

これはログを見ればすぐわかると思います。ただ、iPhoneの純正ケーブルはすぐ接触が悪くなるので、接続しているつもりでも正しく通信出来ていないことがあるかもしれません。

とてもわかりにくいエラーで、日本語環境だとエラーログも文字化けしてしまうので何のことかわかりにくいです。文字化けしていない状態のエラーログにはKeyset does not existと表示され、秘密鍵周りで何かが存在しないと言われていることがわかります。

この場合、以下のフォルダのアクセス権限を確認してください。
C:\ProgramData\Microsoft\Crypto

重要なのはこのフォルダ以下の RSA\MachineKeys のフォルダで、その中に必要なファイルが存在しているはずが、フォルダのアクセス権が間違っているとファイルが空っぽになってしまいます。

Cryptoのプロパティを開き、[セキュリティ]->[詳細設定]を開き、アクセス許可を以下のように書き換えます。

その後、UE4のProject SettingsからCertificateファイルのインポートをやり直すことで、秘密鍵のファイルが正しくコピーされます。

（参考：Resolve Cryptographic Exception ‘Keyset Does Not Exist or Access is Denied issue’）

「指定された状態で使用するには無効なキーです。」という表記が特徴的なこのエラーは、上記の その8 のエラーと同様のもので、最近のUE4のバージョンだとこのように表示されます。Windowsを新規インストールした際などによく発生するようです。

生成されたstub形式のファイルとプロジェクト名が一致しないと発生される不具合のようです。

私の場合、LabyrinthMasterというUE4プロジェクトを作って、Labyrinthというプロビジョニングファイルを使ってビルドした際に発生しました。

エンジンのソースコードを見てみると、どうやら .uproject のファイル名が使われるようなので、あきらめてUE4プロジェクト名をあわせるか、エンジンコードを変更する必要があります。（他の設定で対応可能でしたら教えてください！）

Mac側のホスト名に問題があるようです。

手っ取り早く対応するならば、Windows側のUE4の[プロジェクト設定]＞[Remote Server Name]をホスト名ではなくMacのIPアドレスにすると成功するようになります。

Macのホスト名に関しては、半角スペースが入っているとダメなようです。

Mac側のローカルに保存されているデータを削除してビルドし直します。
