+Future versions of Arvados may require a newer version of Ruby than is packaged with your OS. Using OS packages simplifies initial install, but may complicate upgrades that rely on a newer Ruby. If this is a concern, we recommend using "RVM.":#rvm
+{% include 'notebox_end' %}
+
+h3. Centos 7
+
+The Ruby version shipped with Centos 7 is too old. Use "RVM.":#rvm
+
+h3. Debian and Ubuntu
+
+Debian 9 (stretch) and Ubuntu 16.04 (xenial) ship Ruby 2.3, which is sufficient to run Arvados. Later releases have newer versions of Ruby that can also run Arvados.
