我有两个不同版本的VLC，怎么删除？

Question

在升级到18.04之后，我通过软件商店和终端删除了未使用的应用程序、旧包和其他巡洋舰。我发现VLC与我正在使用的yaru/公报主题不匹配，所以我尝试了一些在Arch上建议的东西，我还从商店安装了VLC快照。我现在有VLC 3.0.4，它与主题相匹配，尽管我仍然有VLC 3.0.3，尽管我通过商店卸载它并使用apt/dpkg检查它。

根据商店的说法，只安装了一个版本的VLC。我如何移除另一个，它是从哪里来的？

好吧，这是令人尴尬的地方:我还从PPA安装了平台运行时，现在我还记得我尝试过平板VLC，但是它与16.04没有很好地集成，所以我忘记了它(希望它将来会改进)。

若要删除，只需运行：

flatpak uninstall org.videolan.VLC

要与Gnome软件集成平台，请安装相应的插件：

sudo apt install gnome-software-plugin-flatpak
