+Since Debian Stretch, `runit` isn't started anymore automatically, but this gets handled by the init system. Additionally, Ruby requires the OpenSSL 1.0 development packages instead of 1.1. For a default installation use these packages:

 The use of Ruby version managers such as [RVM](http://rvm.io/), [rbenv](https://github.com/sstephenson/rbenv) or [chruby](https://github.com/postmodern/chruby) with Huginn in production frequently leads to hard-to-diagnose problems. Version managers are not supported and we strongly advise everyone to follow the instructions below to use a system Ruby.
 
 Remove the old Ruby versions if present:
