yum install GPG NOKEY Error

Many times we receive GPG or V3 DSA signature "NOKEY" Error while Installing packages in CentOS Linux by using yum.

yum install GPG NOKEY Error

Error Example when installing a package that requires a Public Key:

Tested and resolve in :

OS: - CentOS release 4.8 (Solution will work on all version of CentOS)

warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 443e1821

Public key for httpd-2.0.52-41.ent.4.centos4.x86_64.rpm is not installed

Install a public key using the the install disk, example CentOS:

(1) Insert CentOS Install DVD and cd to it.

# cd /media/CentOS-X-version

(2) List contents :

# ls

CentOS GPL images NOTES repodata RPM-GPG-KEY-centos4

centosdocs-man.css headers isolinux RELEASE-NOTES-en.html RPM-GPG-KEY yumgroups.xml

(2) Run the command:

# rpm --import *GPG* RPM-GPG-KEY-xxxxx (look for a RPM-GPG-KEY file in the install Media).

This will import the public keys for the yum installation.

Alternatively you can install the package without GPG Key check:

# yum install (package-name) --nogpgcheck
