错误：在 Fedora 中使用 dnf 升级系统时 GPG 检查失败

今天早些时候，当我尝试升级 Fedora 26 服务器时，下载软件包后收到以下错误消息：

warning: /var/cache/dnf/forensics-5e8452ee3a114fbe/packages/protobuf-c-1.3.0-1.fc26.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 87e360b8: NOKEY

所以我放弃了升级，并尝试dnf clean packages重新下载，但仍然遇到同样的错误。

看来protobuf打包没有有效的签名，因此dnf无法继续，这是正确的吗？

答案1

使用此命令可以解决此问题：dnf update --nogpgcheck

答案2

但是......你说“不”：

Is this ok [y/N]: n

...当要求安装密钥时！

尝试用 yes ( y) 代替！

答案3

我收到以下消息

Package code-1.40.1-1573664332.el7.x86_64.rpm is not signed
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.
Error: GPG check FAILED

所以code包裹没有签名。

让我们看看哪个 repo 提供了它：

dnf provides code | grep "Repo" | sort | uniq

Repo        : code
Repo        : @System

我可以通过禁用code存储库来继续：

sudo dnf update --refresh --verbose --disablerepo code
