GPG 错误，不存在 NO_PUBKEY id

我在 ubuntu 22.04 上遇到一个常见问题：apt-get update由于缺少签名而无法成功执行：

正在读取软件包列表...完成
W：GPG 错误：https://dl.k6.io/debstable InRelease：由于公钥不可用，无法验证以下签名：NO_PUBKEY C780D0BDB1A69C86 E：存储库“https://dl.k6.io/deb stable InRelease”未签名。

我的问题是，引用的键在我的计算机上不存在。输出apt-key list：

我已经尝试执行：sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C780D0BDB1A69C86但令人惊讶的是，它签署了不同的密钥并且没有效果，问题仍然存在：

Executing: /tmp/apt-key-gpghome.4bZH9jxkOQ/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys C780D0BDB1A69C86
gpg: key 77C6C491D6AC1D69: "k6.io (key for signing binaries) <[email protected]>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

我只想消除这个错误，我的机器上甚至没有安装 k6。我搜索到的每个来源都通过重现上述步骤修复了错误...

答案1

我最终删除了 k6 的源列表来解决这个问题：

sudo rm /etc/apt/sources.list.d/k6.list
sudo rm /etc/apt/sources.list.d/k6.list.save
