Package Sign Error

Question

Hi,
I have noticed the next error:
(1/1) checking package integrity                                                                        [#############################################################] 100%
error: ddd: signature from "Eric Belanger <[email protected]>" is invalid
error: failed to commit transaction (invalid or corrupted package (PGP signature))
Errors occurred, no packages were upgraded.
This happens with some packages, while others installs/upgrades normally without an error.
It does not depend on the mainteiner, since others packages from the same maintainer installs correctly.
I have reported a bug with one of this packages: "vlc" and the bug was closed as the maintainer told the package was correct.
It also does not depends on the repo, since the problem arises in different repos.
I have also tried to delete the "/etc/pacman.d/gnupg" directory, and follow the instruction to get it again.
I have also tried to change the keyserver in "gpg.conf".
The problem remains.
Is there any way to manually check the signature of the package?
thanks,

# By default, pacman accepts packages signed by keys that its local keyring

# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
# - URLs will have $repo replaced by the name of the current repo
# - URLs will have $arch replaced by the name of the architecture
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.
