Balking ARM ArchLinux Update

Had an issue with update of ARM ArchLinux which I use here. Error messages like:

Found forum post: many corrupted packages/invalid PGP signatures for aarch64? Suggestion there:

pacman-key --init
pacman-key --populate archlinuxarm

This helped, so could proceed with pacman -Syu.
