After upgrading to 8.16 Jira software shows not installed and clicking the install button results in an error saying refer to the logs but there are no logs generated in /opt/atlassian/jira/log or /var/atlassian/application-data/jira/log
Where to start troubleshooting? I've also entered safe mode thinking it might be a plugin problem but that hasn't fixed the problem.
System is critical and unavailable now. Thanks for your help!
