Looking for suggestions on how to fix my PGP key problems. It has been a few years since I turned on my old Arch Linux machine. I plugged it into the internet and tried to update and of course that's not easy any more.

No package can be updated because there is always a problem with the keyring. I made sure my hardware clock matched the system clock, and then I tried as su to clear the cache and reinitialize the keys
> rm /var/cache/pacman/pkg/*
> rm /etc/pacman.d/gnupg
>paccache -r
> pacman-key --init
>pacman-key --populate

Trying then to update gnupg only gives picrel
>pacman -S gnupg

So in the pic it is now complaining about the new keys it just downloaded into /var/cache... Being corrupt and thus can't update. How can the new keys be corrupt?

Thanks for any help you can give.
