yum install kernel-PAE时：rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

今天在yum install kernel-PAE时出现：

rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

在网上看的解决办法：

This errors occurs sometime with yum install the old GPG keys are obsolote, you have to update them :
由于yum安装了旧版本的GPG keys造成的：

rpm --import /etc/pki/rpm-gpg/RPM* //重导导入一下
