pacman-keyring or what that package is called gets stale really quick over longer periods of time. Large updates are quite smooth in Arch, but IIRC, -Syyu has helped me before.
The extra y just forces a database update. The mechanism to detect when not to update the database is a simple timestamp compare, and shouldn’t break. archlinux-keyring might need a “manual” update if an Arch Linux system is left without updates for a longer period of time. That’s the only situation doing pacman -Sy, then pacman -S archlinux-keyring is recommended, and it needs to be followed with pacman -Syu to avoid a partial upgrade.
Still no reason … unless the repo is volatile, and potentially you have a corrupt version, a simple -Syu is always enough.
Over a year, many repos become relative volatile.
