組み込みデバイスにapt-getを実装しようとしています。テストのためにRaspbianリポジトリの1つを使用していますが、apt-getアップデートで私のキーリングでサポートされていないファイル形式があることを示すメッセージが表示されます。
古いキーリングを削除し、raspbian.orgから新しいキーリングをダウンロードし、apt-keyを使用して追加しました。その結果、gpg（v4）ファイルが作成されました。私の考えでは、apt_2形式ですが、aptはそうではありません。気に入らないようです。
誰かがここで何が起こっているのか、私が一日中何が間違っているのか教えてもらえますか？
挨拶
以下のコンソール出力を参照してください。
