无效签名 EXPKEYSIG

Question

对不起，如果我做了一些愚蠢的事情，但我真的很感激一些帮助。

每当我尝试检查更新时都会出现这种情况

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://download.opensuse.org/repositories/home:/strycore/xUbuntu_18.04  Release: The following signatures were invalid: EXPKEYSIG 2F7F0DA5FD5B64B9 home:strycore OBS Project <home:strycore@build.opensuse.org>

版主注意：wget这里的链接不再可用，因为该存储库不再发布 Ubuntu 18.04 存储库列表或关键数据。但是，由于历史原因，这篇文章的内容被单独留下，不应在评论中标记为“断开的链接”。

您必须访问存储库页面并再次重新添加存储库签名密钥：

wget -nv https://download.opensuse.org/repositories/home:strycore/xUbuntu_18.04/Release.key -O Release.key
sudo apt-key add - < Release.key
sudo apt-get update
