[ovirt-users] Certificate replacing through engine-setup failed

Hi I'm trying to replace the old certificate of the engine, so tha I can again access the management console. I've been reading thorugh a lot of articels and threads and the easiest solution, should be by running the engine-setup. I always get the following error: [ INFO ] Creating CA: /etc/pki/ovirt-engine/ca.pem [ ERROR ] Failed to execute stage 'Misc configuration': Command '/usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh' failed to execute How can I fix this? Thanks in advance for any help! Kind regards, Dominic
