Dependencies 未找到用于生成opencv的依赖项

我正在尝试后续教程以构建opencv，因此我必须首先安装依赖项，因此我打开了一个终端并键入命令，但其中一些命令出现错误，如下所示：

sudo apt get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ught gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5-pulseaudio

sudo apt-y安装libfaac dev libmp3lame dev libthera dev

错误：

您的存储库是否已更新？尝试
