Upgrading from SLES 11 SP4 to SLES 12 SP5 results in certificate error

This document (000019726) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 12 SP5 x86_64


After performing a off-line/down-server upgrade from SLES11SP4 to SLES12SP5, attempts to bootstrap the upgraded system to a SUMA server, or attempts to run the "update-ca-certificates" command result in the following error:

p11-kit: RHN-ORG-TRUSTED-SSL-CERT.pem: Certificate: invalid or unsupported attribute


Edit /etc/pki/RHN-ORG-TRUSTED-SSL-CERT.pem and remove the following line...


... or delete the file altogether.

Once the file is saved or has been deleted, bootstrapping the system to SUMA or running the "update-ca-certificates" command should succeed and a new certificate will be obtained.


After the SLES11SP4 -> SLES12SP5 upgrade procedure, RHN-ORG-TRUSTED-SSL-CERT.pem has a new tag on top of it that is causing issues...


Additional Information

This issue affects both systems that were SUMA clients prior to upgrade, and standalone systems subscribed directly to the SUSE Customer Centre.
