我添加了缺少的键：

$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 1397BC53640DB551
gpg: requesting key 640DB551 from hkp server keyserver.ubuntu.com
gpg: key D38B4796: public key "Google Inc. (Linux Packages Signing Authority) <linux-packages-keymaster@google.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

我仍然收到相同的消息：

sudo dpkg-reconfigure pepperflashplugin-nonfree

你能帮我吗 ？

Answer 1

Pepperflashplugin-nonfree 在/usr/lib/pepperflashplugin-nonfree/pubkey-google.txt. 在使用新密钥更新包之前，您可以通过执行在本地添加密钥

gpg --keyserver pgp.mit.edu --recv-keys 1397BC53640DB551
gpg --export --armor 1397BC53640DB551 | sudo sh -c 'cat >> /usr/lib/pepperflashplugin-nonfree/pubkey-google.txt'

重要的是将新密钥附加到文件 (">>")，旧密钥仍然需要。

在此之后，您可以安装pepperflashplugin

sudo update-pepperflashplugin-nonfree --install

该文件将在包更新时被覆盖，因此如果维护者没有添加新密钥，您可能需要在更新后再次执行此操作（在这种情况下，当新版本正在更新时，您将再次收到相同的错误消息安装）。

Answer 2

你必须使用：

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 1397BC53640DB551
