RPM Package Installation Error: Header V3 RSASHA256 Signature, key ID fd431d51 Nokey

Error message: Header V3 rsa/sha256 Signature, key ID Fd431d51:nokey

First, the problem scenario

RHEL 6.5 Installation MySQL-5.5.44

First, uninstall Rpm-e mysql-libs

Dependencies: (The following five packages will be uninstalled)

cronie-1.4.4-12.el6.i686.rpm

cronie-anacron-1.4.4-12.el6.i686.rpm

crontabs-1.10-33.el6.noarch.rpm

postfix-2.6.6-2.2.el6_1.i686.rpm

sysstat-9.0.4-22.el6.i686.rpm

After installing MySQL-5.5.44 to install the original RPM again, when installing again, in addition to Postfix, the following error occurred:

# RPM-IVH crontabs-1.10-33.el6.noarch.rpm

Warning:crontabs-1.10-33.el6.noarch.rpm:header V3 rsa/sha256 Signature, key ID Fd431d51:nokey

error:failed dependencies:

/ETC/CRON.D is needed by Crontabs-1.10-33.el6.noarch

Second, reason analysis

This is due to the installation of the old version of the GPG keys when Yum initializes the installation.

Third, the solution

First of all:

rpm--import/etc/pki/rpm-gpg/rpm* (introduction of installed public key)

When installing the RPM package again, add --force--nodeps after

# RPM-IVH sysstat-9.0.4-22.el6.i686.rpm--force--nodeps
