当我在ubuntu22.04上的终端上运行：sudo apt update时，我得到了这个错误
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:/Provessor/xUbuntu_20.04 InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 876292BF7F9C32BF
W: http://download.mono-project.com/repo/ubuntu/dists/trusty/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

W: Some index files failed to download. They have been ignored, or old ones used instead.我尝试用以下命令解决问题：sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 876292BF7F9C32BF，但它不起作用，并得到了以下消息
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

我用这些东西解决了我的问题
sudo rm -rf /var/lib/apt/lists/*
sudo rm -rf /etc/apt/sources.list.d/*
sudo apt-get update:)

这个方法是已弃用 for 安全关切：它允许您添加的任何签名密钥都可以签名任何包，而不仅仅是签名密钥存储库中的包。
更安全的方法是将密钥添加到像/usr/share/keyrings/repository-name.gpg这样的位置，然后从您的sources.list文件中引用它。
deb [signed-by=/usr/share/keyrings/some-repo.gpg] http://some.repo/apt dev main了解有关这个sources.list文件格式的更多信息，或查看添加Xpra键和存储库的这个例子。
