我如何获取 ksplice 的公钥？

（我知道安装第三方软件包会带来理论上的安全风险。）

我在用拼接为正在运行的系统应用内核更新。安装后，我无法运行

sudo apt-get update

不再有抱怨：

Get:8 http://www.ksplice.com/apt focal InRelease [3.483 B]              
Err:8 http://www.ksplice.com/apt focal InRelease
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 82562EA9AD986DA3
Reading package lists... Done
W: GPG error: http://www.ksplice.com/apt focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 82562EA9AD986DA3
E: The repository 'http://www.ksplice.com/apt focal InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

这是可以预料到的，我认为我可以通过以下方式安装公钥：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 82562EA9AD986DA3

尽管通过以下方式失败：

gpg: keyserver receive failed: No data

我假设我使用了错误的密钥服务器。我在谷歌上搜索密钥哈希时找不到任何结果，而且用户指南也没有提供任何关于密钥的提示。

我可以在哪里获取 ksplice 的公钥？

NObert 提出的解决方案不起作用，它仍然抱怨：

$ cat ksplice-archive.asc
