我有一个与这里提出的问题类似的问题：为什么 Rhythmbox Coverart 插件不起作用？（Kubuntu）
我在旧笔记本电脑上运行 Lubuntu 16.04 32 位操作系统，我想将其用作“mediacenter/tagger”。我在我的另一台常规 Ubuntu 桌面上使用 Rhythmbox 和 Covert Art 插件，没有任何问题，但是，这次我无法在“Lubuntu 32 位”上激活 Covert Art 插件。这是我的标准 Rhythmbox 安装（和整个插件安装）。
sudo apt-get install rhythmbox
sudo add-apt-repository ppa:fossfreedom/rhythmbox-plugins
sudo apt-get update
sudo apt-get install rhythmbox-plugin-complete
然后 Rhythmbox 就可以顺利启动了，等等。我可以激活 covertart-search 插件（covertart-browser 需要），但是当我尝试激活 Covert Art 浏览器时，我收到了带有感叹号的“无法加载插件”之类的消息。
然后我使用终端从命令行运行 Rhythmbox，以下是完整的日志

我有两个警告和一个错误，但似乎重要的部分是错误消息
ImportError: cannot import name WebKit, introspection typelib not found
我已经检查过 WebKit 包
gir1.2-webkit2-4.0 is already the newest version (2.10.9-1ubuntu1).
所以我尝试使用另一个 webkit 包
sudo apt-get install gir1.2-webkit-3.0:i386
此时 Covert Art Browser 插件已加载，但当我点击界面使用它时，出现了不太好的（分段错误）核心转储
(rhythmbox:5475): Gtk-CRITICAL **: gtk_box_reorder_child: assertion 'old_link != NULL' failed
Erreur de segmentation (core dumped)
任何帮助都将不胜感激。谢谢
编辑：看起来它与这里的问题类似：https://github.com/fossfreedom/coverart-browser/issues/382
所以，WebKit 和 32 位似乎互不相容
