Unable to install packages from pacman due to PGP signature error

Im having the same issue i think his pgp key has expired you might have to wait it out.

Chaotic-AUR: current status

Forwarding this here: One of our signing keys expired today, causing packages to fail to install with the key being marked as "is unknown trust " - we are aware of this and try to get it fixed as soon as possible, while also ensuring a condition like this does not occur again! Edit: working state has been restored.
