更新GPG错误- NO_PUBKEY -存储库发行版没有签名

Question

我有一些问题，更新Ubuntu18.04。这是错误输出

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.

例如，研究类似的问题

如何修正GPG错误“否”？_普布基“？

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

不过，我还是找不到解决那个问题的办法。有什么建议吗？谢谢。
