Defect #20189
Updated by Toshi MARUYAMA almost 8 years ago
After upgrading from a 2.x version of Redmine to 3.0-stable, following the procedures on the [[RedmineUpgrade]] page, and restarting the _thin_ service, now connections to Redmine fail with a 502 Bad Gateway message, and the _thin_ logfile shows: <pre><code> !! Unexpected error while processing request: undefined method `clean_path_info' for Rack::Utils:Module </code></pre> I am running Redmine on Debian 8, another user from the forums was using Ubuntu 14.04. Everyone who has reported this is using _thin_ as the middleware. Here is the output of <code>bin/about</code> <pre><code> Environment: Redmine version 3.0.3.stable Ruby version 2.1.5-p273 (2014-11-13) [x86_64-linux-gnu] Rails version 4.2.3 Environment production Database adapter Mysql2 SCM: Subversion 1.8.10 Cvs 1.12.13 Bazaar 2.7.0 Git 2.1.4 Filesystem Redmine plugins: no plugin installed </code></pre> This was noted in the Help forums This has been noted in the forums message#46545 https://www.redmine.org/boards/2/topics/46545 but no resolution has been posted. This is a severe problem, and I hope it can be resolved without the necessity of rolling back to Redmine 2.x.
