怎么解决？
sudo apt install gstreamer1.0-plugins-good
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good/html/gst-plugins-good-plugins-id3demux.html
所以它必须是gst插件的一部分。

我在Chromebook上安装的Ubuntu/Xenial中运行的gmusicbrowser遇到了这个问题。
我通过从apt安装gstreamer1.0-plugins-ugly，gstreamer1.0-plugins-bad，gstreamer1.0-plugins-good和gstreamer1.0-pulseaudio解决了这个问题。
我还为 FLAC 解码器安装了 Ubuntu-restricted-extras apt 包。
然后，GmusicBrowser可以播放MP3和FLAC。
