system upgrade failing

hello everyone, it hit me recently that when I try to update using `pacman -Syu` I get this error:
```bash
sudo pacman -Syu                         
[sudo] password for mouadh7:

I tried changing my network connection and DNS settings but nothing seems to work.

Re: system upgrade failing

You already have the databases, the issue is that you have an out of date AUR package (docker-desktop) that's blocking the update. You will need to remove that, update, then update/reinstall the AUR package.

the update worked now but I still get the same errors:

sudo pacman -Syu

Re: system upgrade failing

Fix you mirror list, eg. using https://wiki.archlinux.org/title/Reflector

Re: system upgrade failing

Refresh your mirrorlist. It looks like either your selected mirrors are down or restricted and unreachable from your network.
