Getting error on package.xml when running "catkin_ make"

edit

I have just started with ROS and I am following one of my first beginner tutorial "Writing a Simple Publisher and Subscriber (C++)".

I am receiving an error when I run catkin_make or catkin_make install

This is my terminal:

lucadg@luca-Inspiron-3543:~/catkin_ws$ catkin_make install
Base path: /home/lucadg/catkin_ws
Source space: /home/lucadg/catkin_ws/src
Build space: /home/lucadg/catkin_ws/build
Devel space: /home/lucadg/catkin_ws/devel
Install space: /home/lucadg/catkin_ws/install
**Invalid package manifest "/home/lucadg/catkin_ws/src/beginner_tutorials/package.xml": The manifest contains invalid XML:
mismatched tag: line 60, column 2**

Below a copy of my package.xml file which I checked and everything seems to be ok, line 60 is the last word, the closing tag of package.

This is my package.xml

<?xml version="3.0"?>
<package>

  <name>beginner_tutorials</name>
