Ja das ist ok

Strange update message

I just got my Lenovo thinkpad updated on Cinnamon, haven’t updated for about two weeks. After the update, 115 packages, it says, checking keys in keyring, downloading required keys… and I get the strange message "Import PGP key xxxx, “Sergej Pupykin spupykin@archlinux.org”? [Y/n] Who is Sergej pumpkin, have I been hacked???
