steamdeck更新后，无法安装glibc/krfb的问题

此情况适用于动手能力强（已经通过百度修改过/etc/pacman.d/mirrorlist /etc/pacman.conf但对原理一知半解的用户）

经研究，此情况一般由于/etc/pacman.d/mirrorlist中steamdeck源删除，或/etc/pacman.conf中注释掉一堆调用mirrorlist的参数

首先将/etc/pacman.d/mirrorlist中steamdeck源恢复

Server = https://steamdeck-packages.steamos.cloud/archlinux-mirror/$repo/os/$arch

然后将/etc/pacman.conf中识别镜像源中有哪些文件夹的参数恢复(如果你配置了其他镜像源，但是一直没法下载软件，八成是这里的问题）

[jupiter-rel]

Include = /etc/pacman.d/mirrorlist

SigLevel = Never

[holo-rel]

Include = /etc/pacman.d/mirrorlist

SigLevel = Never

[core-rel]

Include = /etc/pacman.d/mirrorlist

[extra-rel]

Include = /etc/pacman.d/mirrorlist

[community-rel]

Include = /etc/pacman.d/mirrorlist

[multilib-rel]

Include = /etc/pacman.d/mirrorlist

恢复完毕后，重新使用pacman安装软件即可
