  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 7

Issue

  • I am trying to register my RHEL system to RHSM using subscription-manager register and receive the below message:-
System certificates corrupted. Please reregister.

Resolution

  • Unregister the system from RHSM:
# subscription-manager unregister
# subscription-manager clean
  • Re-register the system to RHSM:
# subscription-manager register
  • Auto-attach a subscription or attach a subscription by pool ID:
# subscription-manager attach --auto

OR

# subscription-manager attach --pool=<pool-ID>
  • Enable the repositories you need on the system:
# subscription-manager repos --enable <repo-label-1> --enable <repo-label-2> --enable <repo-label-3>
  • If still the issue persist remove all the present certificate files and place the certificate in /etc/pki/product and try the above resolution again.

Root Cause

  • The system's RHSM data became corrupt. Running subscription-manager clean during the unregister/re-register process will remove corrupted data so that system can properly register again.

  • Error "System certificates corrupted. Please reregister." can also result due to corrupt product certificate, replacing the certificate resolves the issue.

  • The system have corrupt certificate file in /etc/pki/product directory.
