Comment 4 for bug 1431670

Thank you for taking the time to file a bug report.

From the log:
 * Starting message broker rabbitmq-server FAILED
check /var/log/rabbitmq/startup_{log, _err}

Can either of you provide those logs to help diagnose and further triage
the issue, please?

Since there is not enough information in your report to begin triage or to
differentiate between a local configuration problem and a bug in Ubuntu, I
am marking this bug as "Incomplete". We would be grateful if you would:
provide a more complete description of the problem, explain why you
believe this is a bug in Ubuntu rather than a problem specific to your
system, and then change the bug status back to "New".

For local configuration issues, you can find assistance here:
