cannot load such file -- config/boot (LoadError)

Hi folks,

I had installed an ubuntu server redmine 12:04

I decided to upgrade to the new version redmine. After following all the steps in this tutorial:

I am getting the below error message. How to proceed?

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- /var/www/redmine/../config/boot (LoadError)    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'    from /var/www/redmine/dispatch.fcgi:3:in `<main>' [Thu Aug 14 15:28:21 2014] [warn] [client 10.0.0.120] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://10.0.0.220/redmine/admin/projects [Thu Aug 14 15:28:21 2014] [error] [client 10.0.0.120] Premature end of script headers: dispatch.fcgi, referer: http://10.0.0.220/redmine/admin/projects

From the path shown in the error, I’m wondering if you didn’t append ‘/public’ to the DocumentRoot in the apache configuration?
