当我第一次安装 Arch 时，我只使用了其中一个，即Server = http://mirror.xeonbd.com/archlinux/$repo/os/$arch.现在我必须将它们全部保存起来/etc/pacman.d/mirrorlist才能从有效的存储库中查找包！现在几乎所有人都回来了404！
阿奇有什么问题吗？

答案1
Arch Linux 镜像存储库经常删除不是最新版本的软件包。 Arch 也不支持部分系统升级，因此明确地说，您需要：
pacman -Syu
要更新所有内容，包括可用软件包和版本的列表，然后：
pacman -S <package>
答案2
请务必先更新密钥：
sudo pacman -Sy archlinux-keyring
sudo pacman -Syu
