**Linux Study之--yum install错误**

**系统环境：Oracle Linux5.4**

**   在通过yum安装软件时出现以下错误：**

**1、yum配置文件**

[root@rh168 yum.repos.d]# cat yum.repo 
    [base]
    name=Oracle linux 
    baseurl=file:///media/Server
    enable=1
    gpcheck=0
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

**2、安装故障**

**\[root@rh168 yum.repos.d\]\# yum install -y unix\***

Public key for unixODBC-kde-2.2.11-7.1.i386.rpm is not installed

\--安装失败！

**3、解决方法**

**从 RPM 版本 4.1 开始，在安装或升级软件包时会检查软件包的签名。如果签名校验失败，你就会看到如下所示  
的错误消息：  
error: V3 DSA signature: BAD, key ID 0352860f  
如果它是新的、只针对文件头的签名，你会看到如下所示的错误消息：  
error: Header V3 DSA signature: BAD, key ID 0352860f  
如果你没有安装合适的钥匙来校验签名，消息中就会包含 NOKEY ，如：  
warning: V3 DSA signature: NOKEY, key ID 0352860f  
在CentOS下有的时候用yum安装软件的时候最后会提示：  
warning: rpmts\_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID\*\*\*\*\*  
这是由于yum安装了旧版本的GPG keys造成的，解决办法就是  
\#rpm --import /etc/pki/rpm-gpg/RPM\***

**\[root@rh168 yum.repos.d\]\# rpm --import /etc/pki/rpm-gpg/RPM\***

**4、重新安装**

**\[root@rh168 yum.repos.d\]\# yum install -y unix\***
