我已经尝试过帖子中的解决方案 如何修复 GPG 错误“NO_PUBKEY”？但它们没有起作用：
$ 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
gpg: keyserver receive failed: Server indicated a failure
$ gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv ^C
$ 23E07629B9E3C9E4^C
$ gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv 23E07629B9E3C9E4
gpg: keyserver receive failed: No data
答案1
您已添加一些第三方存储库到系统。目前其密钥已过期。
因此您必须使用软件和更新禁用此存储库。
答案2
只需更新过期的 gpg 密钥：
curl-fsSLhttps://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
