我無法安裝等離子。安裝應用程序流時出錯

當我安裝 Arch linux 時，我將 GNOME 41 安裝為 GUI。

但我想安裝 KDE Plasma 5。

我以 root 身份執行以下命令：

pacman -S plasma plasma-wayland-session kde-applications

但是執行這個命令會凍結一段時間安裝包appstream-qt 0.14.6-1 x86_64，然後出現一堆錯誤！

我已經複製了所有看起來很重要的錯誤！

There were some errors, so no packages were updated.

幫助！

0.14.6-1 不再是最新版本的appstream-qt軟體包，因此您的軟體包列表已過期。最近的一個是 0.14.6-2。您需要先更新您的系統，pacman -Syu然後pacman -S plasma plasma-wayland-session kde-applications再次執行。
