Adding to this: individual package updates are not supported. Always update your whole system, unless you know what you are doing.
Do you (not you personally) though?
Then maybe the downloaded packages are actually corrupted. You could check if they have plausible file sizes. IIRC pacman will ask you if you want to delete the non-matching files but I’m not entirely sure. They should end up in
/var/cache/pacman/pkg
.
