Nucleus update 2.12.2 -> 2.12.5 #1621

Closed tomikpik closed 5 months ago

tomikpik commented 5 months ago

Hi there, I'd like to perform a remote upgrade of the Nucleus from 2.12.2 to 2.12.5.

The update ends up with the following exception:

com.aws.greengrass.deployment.exceptions.DeploymentException: Nucleus update workflow failed to restart Nucleus. See loader logs for more details
    at com.aws.greengrass.deployment.KernelUpdateDeploymentTask.getDeploymentStatusDetails(KernelUpdateDeploymentTask.java:132)
    at com.aws.greengrass.deployment.KernelUpdateDeploymentTask.call(KernelUpdateDeploymentTask.java:76)
    at com.aws.greengrass.deployment.KernelUpdateDeploymentTask.call(KernelUpdateDeploymentTask.java:36)

    at java.base/java.lang.Thread.run(Thread.java:833)

Unfortunately, I am not able to locate the mentioned "loader logs" to diagnose it further and there is nothing unusual in the greengrass.log Turning the DEBUG logging does not make a difference.

Could you please help me to diagnose it further?

Thank you

Please look for logs from SystemD using journalctl -u greengrass, this is the loader log.

Also look at the log file named aws.greengrass.Nucleus.log

Hello, Nucleus v2.12.5 has a bug where it could cause a crash at startup on certain ARMv8 processors. It might be the issue you were running into and we have fixed the issue in Nucleus v2.12.6.
