Fresh install issue on Ubuntu 16.04

[Ben Harvie]

I had Confluence running on an Amazon linux AMI no problem - however i want to move to a encrypted Ubuntu 16.04 instance and the installer has an error after creating the new database tables - it comes up with no css stylesheet and i click to create an empty site and it gives the following:

I have tried 5x to reinstall / looked at the mysql settings again - JIRA is running on the same host no problem.

Cause

java.lang.IllegalStateException: Cannot call sendError() after the response has been committed
    at org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:462)

I have the full stack trace if needed (was too big to paste)

Hello,

are you sure the MySQL tables are empty when you are reinstalling Confluence ? you might need to drop and recreate the database to make sure it's in a clean state: https://www.liquidweb.com/kb/delete-a-mysql-database-on-linux-via-command-line/

Cheers,

Hi Alexis - Yes I have dropped the database / recreated it several times (each reinstall i would drop and start again).

Still no joy!

Can you provide more logs and some more details on your instance ?

So I actually just resolved it and it is the most annoying fix ever... running the installer in Firefox was my issue - running it in Chrome worked a charm...
