Keep having issues with the welcome package as the keys seemed outdated

Keep having issues with an endeavour package (welcome) and keep having issues with the keys when downloading the package. I have done a pacman-key init and --refresh-keys but still have the same issue.
I also did a cache cleanup but didnt fix it either. The error message is:

error: welcome: signature from "EndeavourOS <info@endeavouros.com>" is unknown trust
:: File /var/cache/pacman/pkg/welcome-2.0.2-1-any.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]

I had the same problem with an installation, that was previously done with Antergos. If you want to solve that you need to download the keyring manually. Then install it with sudo pacman -U endeavouros-keyring-1-4-any.pkg.tar.xz. Then you can add the EndeavourOS Repository to the pacman.conf.

–> is unknown trust

Is it an EndeavourOS install then or Antergos?
