我一直在 Arch Linux 论坛和我的设备架构的特定部分中进行搜索，但没有任何运气。
不幸的是，ARM 特定的 Arch 论坛已经死了……主要的 Arch 论坛不允许我发帖，因为他们告诉我去 ARM 论坛……所以我在那里找不到任何帮助。
我在 Samsung Chromebook 2 上使用 ARMv7 Arch 发行版
直到昨天一切都工作正常。Pacman正在按预期运行和更新一切。
我尝试[multilib]按照 Arch Wiki 说明添加存储库（pacman.conf手动编辑和添加详细信息）
此时我做了
pacman -Syyu
此后，pacman他的行为开始变得不稳定。连接到任何存储库数据库时我总是收到错误。我尝试从镜像列表中手动取消注释特定服务器，并[multilib]从中删除存储库pacman.conf
不走运，什么都没有改变。
所以我重新安装了pacman手动下载软件包wget。
一切正常，pacman已成功重新安装并pacman.conf重置为默认值。
现在，尝试运行pacman -Syu更新系统时，所有服务器都会出现 404 错误。
在尝试注释/取消注释并手动将服务器包含在pacman.conf...中后，运气不佳。
所以我的下一步是按照 Arch Wiki 部分pacman在此处手动重新安装/修复：
https://wiki.archlinux.org/title/pacman#Manually_reinstalling_pacman
我下载了pacman-static（以及所有依赖项），编译并成功安装，一切顺利。
现在，我尝试运行pacman-static，但系统输出命令未找到......这没有任何意义。
我不知道还要做什么来修复pacman或如何运行pacman-static。
互联网工作正常，wget工作正常，浏览正常。
这是我当前的“pacman.conf”

# By default, pacman accepts packages signed by keys that its local keyring
# trusts (see pacman-key and its man page), as well as unsigned packages.
SigLevel = Required DatabaseOptional
LocalFileSigLevel = Optional
#RemoteFileSigLevel = Required
# NOTE: You must run `pacman-key --init` before first using pacman; the local
# keyring can then be populated with the keys of all official Arch Linux ARM
# packagers with `pacman-key --populate archlinuxarm`.
#
# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
# - URLs will have $repo replaced by the name of the current repo
# - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#
# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.

与此同时，我跑了：
pacman-key --init
pacman-key --populate archlinuxarm
重新安装后pacman以确保这些也已更新
请告诉我您需要哪些更多详细信息来帮助我调试和修复此问题pacman。
非常感谢

解决方案：
强制我的pacman.conf配置仅显式检查这些镜像

Server = http://mirror.archlinuxarm.org/$arch/$repo
#Include = /etc/pacman.d/mirrorlist
[extra]
Server = http://mirror.archlinuxarm.org/$arch/$repo
#Include = /etc/pacman.d/mirrorlist
[community]
Server = http://mirror.archlinuxarm.org/$arch/$repo
