ABRT logs messages with "Package <packagename> isn't signed with proper key."



On a RHEL 6 / CentOS 6 system, the main system log file contains the error "Package <packagename> isn't signed with proper key."  The following example was caused by a manual segmentation fault on zsd.

There are two ways to remedy this.

Method 1: Alter the default abrt behavior.  This may be best if you have multiple third-party packages installed and want to ensure all associated application cores are caught.

  1. Edit the file /etc/abrt/abrt-action-save-package-data.conf
  2. Set OpenGPGCheck = no
  3. Reload abrtd with the command: service abrtd reload.

Method 2: Add Zend's GPG key to the rpm and abrtd key caches.

# wget -O /etc/pki/rpm-gpg/zend.key http://repos.zend.com/zend.key
# rpm --import /etc/pki/rpm-gpg/zend.key
# echo '/etc/pki/rpm-gpg/zend.key' >> /etc/abrt/gpg_keys
# service abrtd reload

Testing:  The effectiveness of the methods can be evaluated by manually triggering a segmentation fault with signal 11. The message log should no longer generate errors regarding the package key.  This may interrupt service temporarily and is not advised on production systems.

# pgrep zsd
# kill -11 2310


The ABRT daemon is responsible for handling the application cores created by segmentation faults. By default it will reject cores from applications that don't have a known GPG signature.
