Apologies for asking in the wrong list. The issue is not resolved by updating archlinux-keyring. Trying to install those package still results in the same error. This is what I get even after deleting the package and updating the keyring:

error: lib32-nss: key "Daniel Wallace <danielwallace@gtmanfred.com>" is disabled
:: File /var/cache/pacman/pkg/lib32-nss-3.15.5-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).

No it isn't, Pacman-key used to be broken and now isn't.  You will need to update archlinux-keyring.

Hi,

I hope this is the right list to be posting this in. I was installing
the lib32 version of flash and happened to notice that the following
multilib packages are signed with a revoked key: lib32-nspr, lib32-nss,
lib32-curl.

Regards
