由于存储库“http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release”未签名，我无法更新

Question

每当我尝试更新终端时都会告诉我这个

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:strycore@build.opensuse.org>
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.

'http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04 ./ Release' 未签名的答案并不能解决我的问题。
