I run “sudo pacman -Syyu” and this is what I get:
error: python2-lockfile: signature from “Thorsten Töpper <[email protected]>” is unknown trust
:: File /var/cache/pacman/pkg/python2-lockfile-0.9.1-1-any.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
Is anyone else having this problem? Why do you think the signatures don’t match?
