sudo apt update 签名验证时出错

我该如何解决这个sudo apt update错误？

我已经尝试过帖子中的解决方案 如何修复 GPG 错误“NO_PUBKEY”？但他们没有工作：

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 23E07629B9E3C9E4
[sudo] password for master: 
Executing: /tmp/apt-key-gpghome.QYq1pmnpyE/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 23E07629B9E3C9E4

    您已向系统添加了一些第三方存储库。目前它的密钥已过期。

    因此，您必须使用软件和更新禁用此存储库。

  2. 只需更新过期的 gpg 密钥：

    curl -fsSL https://download.opensuse.org/repositories/home:pzz/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_pzz.gpg > /dev/null
