warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY

新配置一個服務器centos5.5，運行yum -y update出現一個警告信息：

Total                                           2.1 MB/s | 643 MB     05:00

Importing GPG key 0xE8562897 "CentOS-5 Key (CentOS 5 Official Signing Key) <[email protected]>" from /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

 

這是由於yum安裝了舊版本的GPG keys造成的，解決辦法就是

rpm --import /etc/pki/rpm-gpg/RPM*

 

搞定。
