Hi @zhaoxing ,

Welcome to the Atlassian Community.

Sounds like you had an upgrade problem, I would recommend doing what the message says and look into the system logs for the details, fix them, and retry the upgrade.

This error message doesn't really provide any insights into what happened. Your system log might give you more information.

Cheers,
Peter
