Authenticating the upgrade failed. There may be a problem with the network or with the server.

仅供参考：我已经尝试过sudo apt-get install --reinstall ubuntu-keyring。我也尝试将服务器更改为“主服务器”，但它对我不起作用。

  1. 我不确定是否应该推荐接受的答案，因为我认为正常的升级过程会做很多其他事情？

    我遇到了与原始海报相同的问题，发现这是一个丢失（未记录）的 gpg 密钥。有关信息，我安装的系统真的很旧，多年来从 13.10 安装更新，所以我想这就是为什么会有一些公钥问题。

    首先我检查了这两个文件apt-key verify focal.tar.gz.gpg focal.tar.gz

    这表明我缺少检查签名的密钥。

    如果您的文件夹中没有这些文件，您tmp可以下载它们并进行验证：

    http://archive.ubuntu.com/ubuntu/dists/focal-updates/main/dist-upgrader-all/current/focal.tar.gz http://archive.ubuntu.com/ubuntu/dists/focal-updates /main/dist-upgrader-all/current/focal.tar.gz.gpg

    gpgv: Signature made jeu. 03 sept. 2020 15:23:39 CEST
gpgv:                using RSA key 3B4FE6ACC0B21F32
gpgv: Good signature from "Ubuntu Archive Automatic Signing Key (2012) [email protected]"
gpgv: Signature made jeu. 03 sept. 2020 15:23:39 CEST
gpgv:                using RSA key 871920D1991BC93C
gpgv: Can't check signature: No public key

    然后我通过以下方式添加了丢失的公钥：sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C

    之后更新正常运行。
