I run Antergos Linux. When I try to update vivaldi (browser), I get the following error:
error: vivaldi: signature from "Antergos Build Server (Automated Package Build System) <[email protected]>" is invalid :: File /var/cache/pacman/pkg/vivaldi-1.6.689.34-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)). Do you want to delete it? [Y/n]
Suggestions are welcome.
