So, I’m having a problem performing a system upgrade. I have tried ALL the solutions I could find, but when I do:
sudo pacman -Sy archlinux-keyring manjaro-keyring
error: archlinux-keyring: signature from "Erich Eckner (just to sign arch packages) <firstname.lastname@example.org>" is unknown trust :: File /var/cache/pacman/pkg/archlinux-keyring-20171213-1.0-any.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Any help would be greatly appreciated!
