RubyZip 3.0 is coming!
**********************

The public API of some Rubyzip classes has been modernized to use named
parameters for optional arguments. Please check your usage of the
following classes:
  * `Zip::File`
  * `Zip::Entry`
  * `Zip::InputStream`
  * `Zip::OutputStream`

Please ensure that your Gemfiles and .gemspecs are suitably restrictive
to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
See https://github.com/rubyzip/rubyzip for details. The Changelog also
lists other enhancements and bugfixes that have been implemented since
version 2.3.0.

Here's what you can expect from the installation process:

 1. The Apache 2 module will be installed for you.
 2. You'll learn how to configure Apache.
 3. You'll learn how to deploy a Ruby on Rails application.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

   Please add /root/.rbenv/versions/2.6.10/lib/ruby/gems/2.6.0/gems/passenger-6.0.16/bin to PATH.
   Otherwise you will get "command not found" errors upon running
   any Passenger commands.

   Your Apache installation might be broken
   
   You are about to validate Phusion Passenger(R) against the following
   Apache installation:
   
      apxs2     : /usr/bin/apxs
      Executable: /usr/sbin/httpd
      Version   : 2.4.37
   
   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"

RubyZip 3.0 is coming!
**********************

The public API of some Rubyzip classes has been modernized to use named
parameters for optional arguments. Please check your usage of the
following classes:
  * `Zip::File`
  * `Zip::Entry`
  * `Zip::InputStream`
  * `Zip::OutputStream`

Please ensure that your Gemfiles and .gemspecs are suitably restrictive
to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
See https://github.com/rubyzip/rubyzip for details. The Changelog also
lists other enhancements and bugfixes that have been implemented since
