从 putty.org 下载：

master-2021.asc putty-0.76.tar.gz putty-0.76.tar.gz.gpg release-2021.asc

打开终端

gpg --import master-2021.asc

输出：

gpg: key DD4355EAAC1119DE: 4 signatures not checked due to missing keys
gpg: key DD4355EAAC1119DE: public key "PuTTY Master Key <putty@projects.tartarus.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1
gpg: no ultimately trusted keys found

不知道这意味着什么：

4 signatures not checked due to missing keys

但我使用下一个推荐：

gpg --import release-2021.asc

输出：

gpg: key E4F83EA2AA4915EC: public key "PuTTY Releases <putty@projects.tartarus.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1
gpg: no ultimately trusted keys found

然后我尝试验证：

gpg --verify putty-0.76.tar.gz.gpg putty-0.76.tar.gz

输出：

gpg: Signature made Sat 17 Jul 2021 12:32:18 CEST
gpg:                using RSA key E27394ACA3F9D9049522E0546289A25F4AE8DA82
gpg: Can't check signature: No public key

我究竟做错了什么？

我运行 Ubuntu 20.04，刚刚跑了sudo apt update两次，发布了下面的输出。

我的问题：

  • 为什么 2 apt run 不同？（1 到 16 另一个到 4）

（仅供参考：我在sudo apt upgrade两者之间做了一个，但我用 Ctrl+C 取消了它）
