All, I just recently upgraded from 4.3 to 4.5, and while most of the upgrade went smoothly and I didn't see any major issues, I have noticed a few things that are causing problems. The one piece that I had to sneak in to make the install successful, is push my CA and intermediate CA certs into the engine after it came up the first time, but before it fully installed, otherwise it would fail restoring the backup. This is to address using a custom Apache cert for the hosted engine, instead of the default self-signed CA. The biggest issue is with keycloak. To make the upgrade succeed I had to skip keycloak installation, after doing some digging related to this error: "Failed to execute stage 'Misc configuration': 'OVESETUP_OVN/ovirtProviderOvnSecret'" I don't actively use OVN in my environment right now, and I think it is all pretty much in the default install state. This is the same error I get when I loop back to install keycloak now that the engine is up. This is what is in the logs for the last few lines preceding the error and failure event: 2024-01-19 19:09:32,602+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.execute:921 execute-output: ('ovn-sbctl', 'set-connection', 'pssl:6642:[::]') stdout: 2024-01-19 19:09:32,602+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.execute:926 execute-output: ('ovn-sbctl', 'set-connection', 'pssl:6642:[::]') stderr: 2024-01-19 19:09:32,626+0000 DEBUG otopi.context context._executeMethod:127 Stage misc METHOD otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn.Plugin._misc_configure_ovn_timeout 2024-01-19 19:09:32,627+0000 INFO otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn ovirtproviderovn._misc_configure_ovn_timeout:1076 Updating OVN timeout configuration 2024-01-19 19:09:32,628+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.executeRaw:813 execute: ('ovn-sbctl', 'set', 'connection', '.', 'inactivity_probe=60000'), executable='None', cwd='None', env=None 2024-01-19 19:09:32,652+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.executeRaw:863 execute-result: ('ovn-sbctl', 'set', 'connection', '.', 'inactivity_probe=60000'), rc=0 2024-01-19 19:09:32,653+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.execute:921 execute-output: ('ovn-sbctl', 'set', 'connection', '.', 'inactivity_probe=60000') stdout: 2024-01-19 19:09:32,653+0000 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn plugin.execute:926 execute-output: ('ovn-sbctl', 'set', 'connection', '.', 'inactivity_probe=60000') stderr: 2024-01-19 19:09:32,677+0000 DEBUG otopi.context context._executeMethod:127 Stage misc METHOD otopi.plugins.ovirt_engine_setup.ovirt_engine.network.ovirtproviderovn.Plugin._misc_configure_provider 2024-01-19 19:09:32,678+0000 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/network/ovirtproviderovn.py", line 1113, in _misc_configure_provider self._configure_ovirt_provider_ovn() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/network/ovirtproviderovn.py", line 796, in _configure_ovirt_provider_ovn content = self._create_config_content() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/network/ovirtproviderovn.py", line 761, in _create_config_content OvnEnv.OVIRT_PROVIDER_OVN_SECRET KeyError: 'OVESETUP_OVN/ovirtProviderOvnSecret' 2024-01-19 19:09:32,682+0000 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Misc configuration': 'OVESETUP_OVN/ovirtProviderOvnSecret' 2024-01-19 19:09:32,683+0000 DEBUG otopi.transaction transaction.abort:124 aborting 'DNF Transaction' I have spent a fair amount of time researching this but haven't found a specific root cause, or solution on this issue.
