Description of problem: During the leapp_resume.service, at the very end of the upgrade, customer reported a confusing warning: May 6 15:50:54 <HOSTNAME> leapp3[1735]: 2021-05-06 15:50:54.29 WARNING PID: 2126 leapp.workflow.FirstBoot.network_manager_update_connections: Error calling nm-update-client-ids script: Command ['/usr/bin/python3', 'tools/nm-update-client-ids.py'] failed with exit code 1. As per the sosreport, the NetworkManager has been completely removed from that system, and ifcfg files contain the directive NM_CONTROLLED=no. All was going well, but this warning should not be shown in this case, since that python script tries to connect to the NM daemon. Version-Release number of selected component (if applicable): leapp-repository-0.13.0-2.el7_9 How reproducible: 100% for the customer. Not tested internally.
