由於使用者“_apt”無法存取檔案“ffmpeg_4.2.2-1.dsc”，因此以 root 身分執行非沙箱下載。 - pkgAcquire::Run（13：權限被拒絕）

Question

我執行以下命令以 root 身分在 Kali Linux 中取得 ffmpeg。我從以下位置獲取了教程鏈接這個連結

sudo apt-get build-dep ffmpeg sudo apt-get install libfdk-aac-dev sudo apt-get source ffmpeg

錯誤發生在最後一個命令 ( sudo apt-get source ffmpeg)之後

以下是完整輸出 dpkg-source: info: extracting ffmpeg in ffmpeg-4.2.2 dpkg-source: info: unpacking ffmpeg_4.2.2.orig.tar.xz dpkg-source: info: unpacking ffmpeg_4.2.2-1.debian.tar.xz dpkg-source: info: using patch list from debian/patches/series dpkg-source: info: applying 0001-avcodec-arm-sbcenc-avoid-callee-preserved-vfp-regist.patch dpkg-source: info: applying 0002-avcodec-libtwolame-fix-mono-default-bitrate.patch W: Download is performed unsandboxed as root as file 'ffmpeg_4.2.2-1.dsc' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
