Browser try to download .pl file instead of executing it - apache2, perl cgi scripts, ubuntu

My ubuntu version is 15.04.
I followed the steps for configuring the server:

  1. sudo apt-get install apache2

  2. sudo apt-get install libapache2-mod-perl2

  3. sudo apt-get install perl-debug

  4. sudo apt-get install libapache2-mod-perl2-dev

  5. sudo apt-get install libapache2-request-perl libdatetime-perl

  6. mkdir /var/www/cgi-bin

  7. nano

    #!/usr/bin/perl -w
    print "Content-type: test/html\r\n\r\n";
    print "Hello there!<br/>\nJust Testing. <br/>\n";

    for ($i=0; $i<10;$i++)
    print $i."<br/>";

  8. chmod a+x

  9. Edit /etc/apache2/sites-available/000-default.conf

    <VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf

    # vim: syntax=apache ts=4 sw=4 sts=4 sr noet

  10. /etc/apache2/sites-available/default-ssl.conf file is here(line 5-11)

  11. /etc/apache2/sites-enabled/000-default.conf file is here(line 12-37)

  12. Add lines to nano /etc/apache2/apache2.conf file is here(line- (54-78))

  13. In browser, hit

But, the browser downloads the files.
I am unable to understand the problems. Please help.

 print "Content-type: test/html\r\n\r\n";
                      Here is your problem

should be print "Content-type: text/html\r\n\r\n";

goto root and restart the apache server in your machine by the following command

/etc/init.d/apache2 restart
