How to resolve the Passenger module installation problem?

[Zhu J.C.]

By following the tutorial from this link,  I stuck in getting Passenger module installed correctly, error is shown below. So I can't continue to deploy the server.

FYI, the demo app from quick start tutorial can be up and running in my development environment,. How do I proceed? 

$ passenger-install-apache2-module

If the menu doesn't display correctly, press '!'

 ‣ ⬢  Passenger itself

   ⬢  Apache

Checking whether there are multiple Apache installations...

Only a single installation detected. This is good.

   Your Apache installation might be broken

   

   You are about to validate Phusion Passenger against the following

   Apache installation:

   

      apxs2: /usr/bin/apxs2

   

   However, this Apache installation appears to be broken, so this program

   cannot continue. To find out why this program thinks the above Apache

   installation is broken, run:

   

      export ORIG_PATH="$PATH"

      rvmsudo -E /bin/bash

      export PATH="$ORIG_PATH"

      /home/ubuntu/.rvm/gems/ruby-2.3.0/wrappers/ruby /home/ubuntu/.rvm/gems/ruby-2.3.0/gems/passenger-5.0.29/bin/passenger-config --detect-apache2

So what is the output of the commands that it asks you to run at the end?

Thanks a lot for your hint! I tried to install Passenger against the specific Apache version, and the validation is passed.

Validating installation...
