whenever i try to update my OS with pacman -Syyu the following error show

error: lightdm-slick-greeter: signature from "Alexander Epaneshnikov <email@alex19ep.me>" is unknown trust
:: File /var/cache/pacman/pkg/lightdm-slick-greeter-1.5.6-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).

even if i delete it the same error occurs

Just reinstall the archlinux-keyring package by

sudo pacman -S archlinux-keyring

It happens because lightdm-slick-greeter package is signed with a key which is yet to be updated when upgrading the archlinux-package . Usually happens when updating after some time or updating system after offline install . It happened to me too :smile:
