Sometimes particular .rpm package will fail with below error:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186
Here rpm complains that it misses Red Hat release keys which are delivered during instillation and can be imported with below command
# rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
After importing keys, package installation should be possible.
More info about rpm can be find at
- # man rpm
