yum -y update 报错：GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

• The image of centos6.5 is used. The yum source is too old. I want to update it after modification:

yum -y update

• Execution error:

warning: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5


GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

• solution
• vi /etc/yum.repos.d/CentOS-Base.repo
• Change all RPM-GPG-KEY-CentOS-5 in the file to RPM-GPG-KEY-CentOS-6
