我全新安装了 ubuntu 22.04,什么都没变。我按照 flathub 网站上的步骤操作,但出现了这个烦人的错误,让我无法操作。有什么想法吗?谢谢。

这当然不是一个令人讨厌的错误。这是一个重要的错误,它警告你,你正试图向 Ubuntu 22.04 添加一个存储库,但该存储库不适合该版本,因此如果系统没有警告你,可能会破坏你的系统。
如果你再次阅读 Flathub 网站上的说明,你会注意到在 Ubuntu 上安装 Flatpak 不需要添加存储库。它包含在标准的 ubuntu 软件源中,可以使用以下命令安装
sudo apt install flatpak
这已经启用了 flatpak。接下来你可以添加 flathub 存储库:
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
这简化了从终端安装该存储库的 flatpaks 的过程。
您也可以选择安装 gnome-software 和 flatpak 插件。这样您就可以从 Gnome Software 安装 flatpak,并自动更新它们。
sudo apt install gnome-software-plugin-flatpak
