Arch Linuxdeveloper signature errors

Every now and then when applying updates to my Antergos (Arch) Linux desktop I get an error like

$ sudo pacman -Syyu
error: libvirt: signature from "Christian Rebischke (Arch Linux Security Team-Member) <>" is unknown trust
:: File /var/cache/pacman/pkg/libvirt-4.6.0-3-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]

Accepting the default option means the update fails. If using the GUI client there’s just a message saying the update failed with no further explanation

It is fixed by

$ sudo pacman -S archlinux-keyring

This kind of error is one reason why I’d never consider using Arch in a work environment.
