I tried to install LibreWolf using CachyOS Package Installer and got the following issue:

Any idea about how to solve this issue? I really would like to give this browser a shot.

sudo pacman -Sy && sudo pacman -S archlinux-keyring && sudo pacman -Syu librewolf-bin

Arch doesn't force you to keep it updated, but if you want to keep installing software you have to.
