    Metadata details:
    filename: fix_sudo_enabled_trusty.rb
    path of file: ./repos/travis-build/lib/travis/build/appliances
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'travis/bui
    
        def apply
          sh.if sh_is_linux? do
            sh.if sh_is_trusty? do
              sh.cmd 'unset _JAVA_OPTIONS', echo: false
              sh.cmd 'unset MALLOC_ARENA_MAX', echo: false
            end
          end
