I can't update due to The repository 'http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release' is not signed

Question

Whenever I try to update terminal tells me this

Ign:20 http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release.gpg
Reading package lists... Done 
W: GPG error: http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release: The following signatures were invalid: EXPKEYSIG 2F7F0DA5FD5B64B9 home:strycore OBS Project <home:[email protected]>
E: The repository 'http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

The answer here 'http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release' is not signed does not solve my problem.

Solution

The key is expired, you could try downloading it again.

wget -qO - https://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04/Release.key | sudo apt-key add -
sudo apt-get update

I get "gpg: no valid OpenPGP data found." I'm on Ububntu 18.04
