Some Antergos users have been reporting the following (or very simular) issue this weekend:
error: antergos-keyring: signature from "Antergos Build Server (Automated Package Build System) <admin@antergos.org>" is unknown trust
This can easily be cured with a little pacman based house keeping. The package cache needs to be cleaned up and a refresh of the pacman keys needs to be made.
$ pacman -Scc
$ pacman -Syy
$ pacman-key --refresh-keys
$ pacman -Syu
Some users on the forums have recommended doing this periodically to prevent issues coming out of the woodwork and suprising you.
