Your environment passed all requirements. Remove or rename the /usr/local/pnp4nagios/share/install.php file now.

go to terminal: sudo nautilus -> go to this page and rename file


Config
Still go to terminal: sudo nautilus.

Go to /usr/local/nagios/etc/nagios.cfg,
Change default fields to this content:

process_performance_data=1
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tHOSTOUTPUT::$HOSTOUTPUT$
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$\tSERVICEOUTPUT::$SERVICEOUTPUT$
host_perfdata_file_mode=a
service_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
service_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file
service_perfdata_file_processing_command=process-service-perfdata-file

Go to /usr/local/nagios/etc/objects/commands.cfg, append the command definitions:

define command {
command_name    process-service-perfdata-file
command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
}

define command {
command_name    process-host-perfdata-file
command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

go to /usr/local/pnp4nagios/etc/ , rename rra.cfg-sample files to rra.cfg.


Append two entries to /usr/local/nagios/etc/objects/templates.cfg:

define host {
name            host-pnp
action_url      /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
register        0
}

define service {
name            service-pnp
action_url      /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register        0
}

Add above templates to any host or service you want like I change /usr/local/nagios/etc/objects/localhost.cfg

.......
define host{
        use                     linux-server,host-pnp         ; Name of host template to use
                            ; This host definition will inherit all variables that are defined
                            ; in (or inherited by) the linux-server host template definition.
        host_name               localhost
        alias                   localhost
        address                 127.0.0.1
        }

......
define service{
        use                             local-service,service-pnp          ; Name of service template to use
        host_name                       localhost
        service_description             PING
    check_command            check_ping!100.0,20%!500.0,60%
        }
........

Restart nagios and apache2 services like aboves and we will see graph icon in hosts and services was added template.
This is the result:
