چطور درستش کنم ؟؟

مخزنت به‌روز نیست.
یک مخزن دیگه بزن.

مثلاً:

Server = https://mirrors.bfsu.edu.cn/archlinux/$repo/os/$arch
sudo pacman -Syu
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 multilib is up to date
 world.db failed to download
error: failed retrieving file 'world.db' from mirror.parchlinux.ir : Resolving timed out after 10000 milliseconds
error: failed retrieving file 'world.db' from mirror.parchlinux.com : SSL certificate OpenSSL verify result: certificate has expired (10)
error: failed to synchronize all databases (failed to retrieve some files)
