I would like to troubleshoot why the installer is failing though. If you can give me any errors you might encounter inside error.log from /var/logs/apache2/ I would appreciate it.
After hitting submit, do you see any popup? If so, what is the general gist of the message? “Settings NOT saved”?
If you are getting a quick popup or no popup I suspect it might be related to my forced SSL setting. When index.php loads it checks if the base url is an https or http. If it is http it forces over to https and if your web server is not configured for SSL that might be the error. I figured it would be safer to send authentication information over SSL and I just realized I do not currently force the installer to use SSL.
