Any way to force pacman to prefer IPV6?

I'm using IPV6-able mirrors

is it possible to force pacman to use IPV6 only, other than disabling IPV4 in the whole system?

You could use a custom XferCommand command per PACMAN.CONF(5) with wget using -6

Something like this might work:

XferCommand = /usr/bin/wget -6 -c -O %o %u
- tyvm
  
  seems to be working, even with some 404s returned

  Does that only happen when it tries to download files ending in .db.sig? If so, I think I read somewhere that db have no sig. So as long as it otherwise works, this error is cosmetic.
Why would you want to do that? pacman attempts to connect via IPv6 first anyway.

This should be the default systemwide.

Is your IPv6 behind NAT (like on a VPN)? See https://wiki.archlinux.org/title/Mullvad#Preferring_IPv6_inside_the_tunnel
