Ruby 24 Package Deprecated — Use ea-ruby27-mod_passenger for Ruby > 2.7

Issue

You may encounter a message like:

Package alt-ruby not installed. Install Ruby Selector for cPanel.

This typically means that the Ruby packages required to support Ruby applications under cPanel (via the Ruby Selector) are missing.

Environment

• Ruby Selector

Solution

What changed

• The older package, ea-ruby24-mod_passenger (which provided support for Ruby 2.4), is deprecated.
• For modern Ruby applications using Ruby 2.7 or newer, the recommended package is now ea-ruby27-mod_passenger. 
• On systems running CloudLinux OS Shared OS 8 (or newer), only ea-ruby27-mod_passenger is supported.

What to do

1. Install the Ruby Selector and Passenger for Ruby 2.7 using your package manager. For example:

yum install ea-ruby27-mod_passenger
cagefsctl --force-update

1. If you previously relied on ea-ruby24-mod_passenger, migrate your applications to Ruby 2.7 (or newer).

   Once everything is verified, you can safely stop using the deprecated Ruby 2.4 package.

Why this matters

• Ruby 2.4 is officially end-of-life and no longer receives security updates. Continuing to use it can leave applications vulnerable.
• By using Ruby 2.7 (or newer) with Passenger, you ensure better compatibility, security, and performance for your Ruby web applications under cPanel.
• An upcoming release for EasyApache4 and mod_passenger will be updated for ruby 3.4.5
