Installing xml-extension (php7.0-xml in my case) solved the problem

sudo apt-get install php-xml

If PHP version is 7.2, execute the following command

sudo apt-get install php7.2-xml

Managed to fix it with a php version 5.6* :

$ sudo apt-get update
$ sudo apt-get install php5.6-xml

You might have some missing dependencies, so first run 

sudo apt-get -f install

Then install php-xml

sudo apt-get install php-xml

This worked for me.

DOM is a PHP extension and not a PHP package. This means that your version of PHP needs to be recompiled with the extension. It is possible however that your PHP was already compiled with DOM but that DOM is not enabled. You can check this in your php.ini (search for extension=dom.so and make sure it's uncommented).

In my case I use

sudo apt-get update

and

sudo apt-get install php7.3-xml
