更新 GPG 错误 - NO_PUBKEY - 存储库发布未签名

我在更新 Ubuntu 18.04 时遇到了一些问题。以下是错误输出

W: GPG error: http://download.opensuse.org/repositories/home:/strycore/xUbuntu_18.04 ./ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2F7F0DA5FD5B64B9
E: The repository 'http://download.opensuse.org/repositories/home:/strycore/xUbuntu_18.04 ./ 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.

如何修复 GPG 错误“NO_PUBKEY”？

不起作用。具体来说，我得到了错误

nik@nik:~$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2F7F0DA5FD5B64B9
Executing: /tmp/apt-key-gpghome.uWb8bIzMR8/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 2F7F0DA5FD5B64B9
gpg: keyserver receive failed: No data

nik@nik:~$ gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv 2F7F0DA5FD5B64B9
gpg: keyserver receive failed: No data

但我找不到解决该问题的方法。有什么建议吗？谢谢。
