Redmine

Hi,
I was upgrading redmine from 3.3.1 version to 3.3.2 version. I followed as always steps wrote here http://www.redmine.org/projects/redmine/wiki/RedmineUpgrade but I noticed that the during the installation of gems it required for ruby >=2.1 (I had 2.0.0).

So I updated ruby with rvm and I was able to go ahead.
But when I recreate the secret token I've an error.

bundle exec rake generate_secret_token

/usr/local/rvm/gems/ruby-2.2.0/gems/htmlentities-4.3.1/lib/htmlentities/mappings/expanded.rb:465: warning: duplicated key at line 466 ignored: "inodot" 

The same things happen trying to update the database:

bundle exec rake db:migrate RAILS_ENV=production
/usr/local/rvm/gems/ruby-2.2.0/gems/htmlentities-4.3.1/lib/htmlentities/mappings/expanded.rb:465: warning: duplicated key at line 466 ignored: "inodot" 
(eval):53: warning: duplicated key at line 53 ignored: :format

I should move on or are errors that should be fixed?

Thanks
