If I enter sudo pacman-mirrors -f && sudo pacman -Syyu, the system updates the repos and d/l the updates as usual but then I get dozens of errors such as:
error: iana-etc: signature from "Jelle van der Waa <jelle@archlinux.org>" is unknown trust
:: File /var/cache/pacman/pkg/iana-etc-20230803-1-any.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
error: glibc: signature from "Frederik Schwan <freswa@archlinux.org>" is unknown trust
:: File /var/cache/pacman/pkg/glibc-2.38-3-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
I hit default (Y) on what seemed like dozens of these errors and tried again but nothing I do gets rid of these errors returning.
