私の Raspberry Pi 4 (Ubuntu MATE 22.04 OS) のカメラ スクリーニングには 2 つの大きな問題があります。
1: libcamera を正常にインストールし、フォルダーと ls に表示されていますが、実行したいときに毎回「コマンドが見つかりません」というエラーが表示され、実行できません。5 回ほど再インストールを試みましたが、うまくいきませんでした。
2: ロボットでカメラを起動するコマンドを実行すると、カメラが起動するまで表示されますが、開発マシンには画像が送信されません。

/boot/firmwware/config.txt ファイルを camera_auto_detect=0 に変更し、start_x=1 を追加しましたが、それでもカメラとすべてが検出されましたが、起動しようとすると、カメラが起動するまで進み、停止して画像が表示されません。
何かアイデアがあれば助けてください
libcameraとドライバーを5回ほど再インストールしてみましたが、毎回ドライバーによってすべてが機能し、起動だけが機能しません
ターミナルからのトレースバック: vcgencmd get_camera サポート=1 検出=1、libcamera インターフェース=0
libcamera-hello libcamera-hello: コマンドが見つかりません
