[SOLVED]pacman -Syu multilib.db core.db cant be retrieved/unrecognized

I don't even know why this error happens. This is the first time I have seen it, and I don't think I did anything stupid to generate this error. I was trying to update my packages like usual via `sudo pacman -Syu`, but suddenly, I got this error:

 sam@ALSam  ~  sudo pacman -Syu
[sudo] password for root: 
:: Synchronizing package databases...
 core                                                                         7.4 MiB  12.6 MiB/s 00:01 [##############################################################] 100%
 extra is up to date
 multilib is up to date
error: failed retrieving file 'multilib.db' from mirrors.pablonara.com : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds
:: Starting full system upgrade...
error: could not open file /var/lib/pacman/sync/core.db: Unrecognized archive format
error: failed to prepare transaction (invalid or corrupted database)

Can anyone tell me what is happening, and how do I troubleshoot and fix this?

Thank you so much!

It look like your chosen mirror is currently not working correctly. Select another one and resync again.

I just did it, and now I got this error:

 ✘ sam@ALSam  ~  sudo pacman -Syu
:: Synchronizing package databases...
 core is up to date

Here is what I see in /var/lib/pacman/sync/core.db:

Re: [SOLVED]pacman -Syu multilib.db core.db cant be retrieved/unrecognized

stat /var/lib/pacman/sync/core.db
file /var/lib/pacman/sync/core.db

And you've official permission (well… by me) to try

sudo pacman -Syyu

(the second "y" forces a database update, even if it looks up to date)

stat /var/lib/pacman/sync/core.db
file /var/lib/pacman/sync/core.db

I got this:

Thank you for this. It works. I run sudo pacman -Syu after and it runs flawlessly.

I did the stat and file again after, and this is what I get:
