error: failed retrieving file 'core.db' from mirror.archlinu

[linuxero]

Hi how are things! I'm new to using Arch and I'm trying to use it on a raspberry pi 4b When trying [quote]-Syu [/quote]I get the output:

[code] :: Synchronizing package databases... core.db failed to download error: failed retrieving file 'core.db' from mirror.archlinuxarm .org : Resolving timed out after 10000 milliseconds error: failed to synchronize all databases (download library error)[/code]

and the same when doing [code]-Syy[/code]
I have also tried:
[code]pacman -Sy archlinux-keyring --noconfirm[/code]
with the same result
I hope you can help me, I appreciate your attention in advance.
