I recently added chaotic-aur and when I try to uddate my system I get the following error
error: dropbox: signature from "Pedro Henrique Lara Campos <root@pedrohlc.com>" is unknown trust
:: File /var/cache/pacman/pkg/dropbox-112.4.321-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] y
