+Ruby 2.7 or newer is required.
 
-Either log out and log back in to activate RVM, or explicitly load it in all open shells like this:
+* "Option 1: Install from packages":#packages
+* "Option 2: Install with RVM":#rvm

+
+h3. Alma/CentOS/Red Hat/Rocky
 
-Once RVM is activated in your shell, install Bundler:
+Version 7 of these distributions does not provide a new enough Ruby version.  Use "RVM":#rvm to install Ruby 2.7 or newer.
+
+Version 8 of these distributions provides Ruby 2.7. You can install it by running:
 
 <notextile>
-<pre><code>~$ <span class="userinput">gem install bundler</span>
-</code></pre></notextile>
+<pre><code># <span class="userinput">dnf module enable ruby:2.7</span>
+# <span class="userinput">dnf install --enablerepo=devel ruby ruby-devel</span></code></pre>
+</notextile>
+
+h3. Debian and Ubuntu
 
-h4(#fromsource). *Option 2: Install from source*
+Debian 10 (buster) and Ubuntu 18.04 (bionic) ship with Ruby 2.5, which is too old for Arvados. Use "RVM":#rvm to install Ruby 2.7 or newer.
 
-Install prerequisites for Debian 8:
+Debian 11 (bullseye) and Ubuntu 20.04 (focal) and later ship with Ruby 2.7 or newer, which is sufficient for Arvados.
