错误提示：

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 1e5e0159

base/gpgkey | 1.5 kB 00:00

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*
