当我安装 Arch linux 时，我安装了 GNOME 41 作为 GUI。
但我想安装 KDE Plasma 5。
我以 root 身份运行以下命令：
pacman -S plasma plasma-wayland-session kde-applications
但是执行这个命令会在安装包时冻结一段时间appstream-qt 0.14.6-1 x86_64，然后出现一堆错误！
我已经复制了所有的错误，一切看起来都很重要！

Attention: Failed to get some files
error: failed to commit transaction (failed to download some files)
There were some errors, so no packages were updated.
