I’ve tried to update system and got error for antergos packages:
error: gnome-shell-extension-dash-to-dock: signature from “Antergos Build Server (Automated Package Build System) email@example.com” is unknown trust
:: File /var/cache/pacman/pkg/gnome-shell-extension-dash-to-dock-1:v47-1-any.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
I’ve tried solution from this topic:
Cannot upgrade: “invalid or corrupted package” , but it doesn’t work.
