Lutris APT repo key expired

after running a sudo apt update i noticed this

W: Failed to fetch http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04/./Release.gpg The following signatures were invalid: KEYEXPIRED 1484261108

plz update key

thanks

This is now fixed, everyone should reimport their repo key to get rid of errors

What are the commands to do so, please?

The commands are here: https://lutris.net/downloads/

Thank you!
