redhat yum install - GPG 密钥检索失败

Question

我试图在 Linux 机器上 yum 安装 etckeeper。详情如下。

密钥检索时安装失败。

我想知道为什么密钥文件被寻址为 file:///etc/pki/。密钥文件不是应该通过http检索吗？

[me@linux ~]$ sudo yum install etckeeper

尝试手动导入

# rpm --import http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6

Answer 2

您也可以简单地使用命令安装 yum install --nogpgcheck {packagename}

Answer 3

您必须先安装 epel-release 软件包才能安装 GPG-Keys：

sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
