Edit 1: If you are using linuxbrew, check that you do not have gnupg package installed as it will clash
brew uninstall --ignore-dependencies gnupg
It appears the GPG key 3FEF9748469ADBE15DA7CA80AC2D62742012EA22 is permanently untrusted and cannot be forced trusted.
You need to clone the AUR git repo, then run the following command in the repo
makepkg -si --skippgpcheck
That will install the packages at least.
