MATE installation - Corrupted package

While installing MATE, when I do

sudo pacman -Syu mate mate-extra

after the packages and dependencies are downloaded, I am shown this error:

Do you want to delete it? [Y/n] 

What am I missing here?

Re: MATE installation - Corrupted package

There is a new packager, whose key you did not have on your system (and pacman failed to download).  Updating the keyring package gave you that key, and allowed you to install the package.
