I had trouble installing alfaview on a new system due to PGP signature / no key. I read that AUR helpers such as yay try to import required keys on the fly. This did not work in my case. Might it help to add a validpgpkeys statement to your PKGBUILD?

Alfaview needs to be started with "-platform xcb" argument on wayland.
