Hi guys Just to let you know that both stable & testing fail to setup hosted engine very early in the process, in Centos 9 [ ERROR ] b'[WARNING]: Skipping plugin (/usr/share/ovirt-hosted-engine-\n' [ ERROR ] b'setup/he_ansible/callback_plugins/2_ovirt_logger.py), cannot load: cannot\n' [ ERROR ] b"import name 'Callable' from 'collections'\n" [ ERROR ] b'(/usr/lib64/python3.11/collections/__init__.py)\n' [ ERROR ] b"ERROR!
