无法在 arch linux 上使用 gpg 导入密钥

Question

我是一个拱形 4.9.8-1 系统。我想为 gpu passthrough 安装 linux-vfio 内核并解决 IOMMU 组错误的问题。

尝试安装 linux-vfio 内核时，由于缺少密钥，出现以下错误。

$ yaourt -S linux-vfio
.
.
.
==> Verifying source file signatures with gpg...
    linux-4.9.tar ... FAILED (unknown public key 79BE3E4300411886)
    patch-4.9.8 ... FAILED (unknown public key 38DBBDC86092693E)

我一直在尝试用 gpg 导入一个密钥，现在我尝试了很多不同的东西，但我一直遇到同样的错误，我用 pacman 安装了 gnupg 包。

$ gpg --recv-key 79BE3E4300411886
gpg: keyserver receive failed: Connection refused

$ gpg --keyserver pgp.mit.edu --recv-keys 79BE3E4300411886
gpg: keyserver receive failed: Connection refused

检查服务器是否可用

$ gpg-connect-agent --dirmngr
> keyserver --resolve hkp://pool.sks-keyservers.net
S # https://hkps.pool.sks-keyservers.net:443
OK
> 

和调试

$ gpg -vvv --debug-all --recv-keys --keyserver http://pgp.mit.edu 79BE3E4300411886

有谁知道如何解决这个问题？

您可以手动导入您的密钥。转到https://pgp.mit.edu/并使用以下字符串进行搜索： ，单击第一个链接，然后将公钥服务器网页0x00411886的内容复制到您喜欢的文本中编辑。另存为linux-vfio.asc

最后运行：gpg --import linux-vfio.asc导入密钥。
