Unable to upgrade packages



I am getting an error in the lines of

error: xf86-input-synaptics: signature from "Laurent Carlier <lordheavym@gmail.com>" is unknown trust
:: File /var/cache/pacman/pkg/xf86-input-synaptics-1.9.0-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted 
package (PGP signature)).
Do you want to delete it? [Y/n] y
error: failed to commit transaction (invalid or corrupted package (PGP signature))
Errors occurred, no packages were upgraded.

for almost all packages.

I might have messed up something. Can someone help me fix this so I can install packages?



See this post in this forum: Update / pacman / keyring problem


And let us know if that fixed it…
