Hi Martin, OK. I chose `java-11-openjdk.x86_64` for java and javac. `make` progress went pretty well until completed. Now I come to setup `$ "${PREFIX}/bin/engine-setup"`, but I failed after `--== CONFIGURATION PREVIEW ==--`: Please confirm installation settings (OK, Cancel) [OK]: [ INFO ] Stage: Transaction setup [ INFO ] Stage: Misc configuration (early) [ INFO ] Stage: Package installation [ INFO ] Stage: Misc configuration [ INFO ] Upgrading CA [ INFO ] Creating CA: /home/yongsheng/f419/etc/pki/ovirt-engine/ca.pem [ INFO ] Creating CA: /home/yongsheng/f419/etc/pki/ovirt-engine/qemu-ca.pem [ INFO ] Setting up ovirt-vmconsole proxy helper PKI artifacts [ INFO ] Setting up ovirt-vmconsole SSH PKI artifacts [ INFO ] Configuring WebSocket Proxy [ INFO ] Creating/refreshing Engine database schema [ INFO ] Updating OVN SSL configuration [ INFO ] Updating OVN timeout configuration [ ERROR ] Failed to execute stage 'Misc configuration': [Errno 2] No such file or directory: '/home/yongsheng/f419/var/lib/ovirt-engine/external_truststore' [ INFO ] Rolling back database schema [ INFO ] Clearing Engine database engine [ INFO ] Stage: Clean up Log file is located at /home/yongsheng/f419/var/log/ovirt-engine/setup/ovirt-engine-setup-20230418170928-1v6iod.log [ INFO ] Generating answer file '/home/yongsheng/f419/var/lib/ovirt-engine/setup/answers/20230418175134-setup.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Execution of setup failed Any idea about external_truststore?
