The error message “A start job is running for Network Manager Wait Online” indicates that the network manager service is waiting for a network connection to be established before it can start. This is usually a normal part of the boot process and should not cause any major issues with your system.
However, if you are experiencing issues with your network connectivity, you may want to check your network settings or consult with a technician for further assistance. Additionally, if you are trying to run a script or command using rc.local and it depends on the network connection being available, you may need to add a delay or wait statement in your script to ensure that the network connection has been established before executing the rest of the commands.
